GEOFF BENNETT: Good evening.

I'm Geoff Bennett.

AMNA NAWAZ: And I'm Amna Nawaz.

On the "NewsHour" tonight: The death toll from the devastating earthquake from Morocco rises further, as rescue operations struggle to reach those in need.

YASSIN NOUMGHAR, Earthquake Survivor (through translator): Everything is gone.

We lost the entire house.

There are no officials visiting us.

There is no help or aid.

GEOFF BENNETT: President Biden wraps up his overseas travel to the G20 and Vietnam, a trip that aimed to shore up Pacific alliances in the face of China's growing influence.

AMNA NAWAZ: And more than two decades after 9/11, the men accused of plotting the attacks remain in legal limbo at Guantanamo Bay, while potential plea deals are negotiated.

(BREAK) AMNA NAWAZ: Welcome to the "NewsHour."

The aftershocks of the deadly earthquake that hit Morocco Friday night continued today, as the death toll approached 3,000.

That number is expected to rise further, along with the number of injured.

GEOFF BENNETT: The rescue and recovery operations continue tonight, but at a slow pace.

And that's a source of frustration and anger for many Moroccans, who say their government is not doing enough.

Special correspondent Alex Cadier reports from Marrakesh.

ALEX CADIER: For a second night since the quake, crowds of displaced people crammed into the streets of Tinsmiths Square in Marrakesh, left homeless by the 6.8-magnitude tremor, the worst since 1960, and with only blankets to keep them warm.

Survivors waited out aftershocks for aid to arrive.

YAHYA ELMA, Earthquake Survivor: We need the help, because every family here don't have the house.

Every house here is broken.

ALEX CADIER: By morning, the scope of damage now in plain view.

Narrow alleyways in the Medina, a UNESCO World Heritage Site, reduced to rubble, old ornate rooftops now crumbled.

The earthquake's epicenter was just south of Marrakesh in the remote province of Al Haouz.

Towns nestled deep in the Atlas Mountains, with homes built mostly from mud bricks, completely collapsed.

Hamid Ben Henna recalled the terrible moment the quake struck, destroying his home and killing his son, just 8 years old.

HAMID BEN HENNA, Earthquake Survivor (through translator): We were having dinner.

I asked my son to bring a knife from the kitchen to cut dessert.

He didn't bring it because, as soon as he left the kitchen, the earthquake struck.

He ran here, where you can see rubble.

He was buried in two meters of rubble.

ALEX CADIER: For these villagers, rescue efforts are agonizingly slow.

Access roads blocked by landslides make the task of reaching these already remote areas even more daunting.

With no heavy equipment, some took matters into their own hands.

Mohamed Ouchen described how he rescued his sister immediately after the quake.

MOHAMED OUCHEN, Earthquake Survivor (through translator): We did not have tools, so we used our hands.

Her head was visible, so we kept digging by hand.

ALEX CADIER: Many locals have been moved to small tent encampments nearby.

MOHAMED AIT SI BOURHIM, Earthquake Survivor (through translator): Now we need tents for people to stay in.

We need shelters for women and children, because people are sleeping outdoors.

ALEX CADIER: Entire families sleeping rough, fearing aftershocks and worried about their uncertain future.

Over the past few days, rescuers have raced into the hardest-hit areas to help, at times pulling bodies from underneath mounds of broken bricks, and meticulously listening for signs of life buried in the rubble.

But with many still in need of aid, some have criticized Morocco's response to this historic disaster.

Today, Prime Minister Aziz Akhannouch vowed to compensate those affected by the earthquake.

But the government has refused to accept foreign aid from all but four countries, Qatar, the United Arab Emirates, the United Kingdom and Spain.

Moroccan officials hoped the strategy would avoid a -- quote -- "counterproductive lack of coordination."

Crews have finally made it to some remote villages after painstaking delays.

ANTONIO NOGALES, Spanish Rescue Worker (through translator): It is very remote, and it took us about eight hours to get here.

There were no rescue groups, and we arrived with the police.

The destruction is absolute.

All the buildings have collapsed.

ALEX CADIER: As aid trickles in, the official death toll is expected to rise, and the extent of destruction clearer.

For now, survivors have no choice but to wait as they grapple with what they have lost.

YASSIN NOUMGHAR, Earthquake Survivor (through translator): Everything is gone.

We lost everything.

We lost the entire house.

There are no officials visiting us.

There's no help or aid.

This is the will of God.

ALEX CADIER: For the "PBS NewsHour," I'm Alex Cadier in Marrakesh, Morocco.

AMNA NAWAZ: In the day's other headlines, catastrophic flooding from a powerful storm has hit Eastern Libya.

The Red Cross reports at least 150 people have been killed, and one of the country's rival prime ministers says up to 2,000 may be dead.

Images from the city of Derna today showed widespread devastation, with floods and mudslides sweeping away entire neighborhoods.

Officials said 5,000 people may be missing.

The same storm flooded parts of Greece, Turkey and Bulgaria last week.

Here at home, the nation marked 22 years since the attacks of September 11.

For many Americans, it was a day for solemn ceremonies and sometimes tearful remembrances.

Laura Barron-Lopez has our report.

LAURA BARRON-LOPEZ: The horrors of that September day in 2001 remembered on this 22nd anniversary.

MAN: Petty officer 3rd Class Jamie L. Fallon.

LAURA BARRON-LOPEZ: Nearly 3,000 people died when planes hijacked by al-Qaida terrorists crashed into New York's World Trade Center, the Pentagon, and a rural Pennsylvania field, making it the deadliest terror attack on U.S. soil.

ANITA JAGGERNAUTH, Daughter of September 11 Victim: I lost my dad here.

It will never get easy.

It's the same thing all over again.

It hurts.

LAURA BARRON-LOPEZ: Vice President Kamala Harris was among those who gathered to pay their respects at Ground Zero in Manhattan.

Keeping with tradition, family members read the names of the dead aloud.

BRIAN MACLEOD, Former NYPD Officer: I needed to be here.

LAURA BARRON-LOPEZ: Brian MacLeod, a former New York City police officer, returned to the site for the first time in more than two decades.

BRIAN MACLEOD: I haven't stepped foot on this grounds since October of 2001.

LAURA BARRON-LOPEZ: In Arlington, Virginia, crews unfurled a giant American flag.

A ceremony paid tribute to the 184 lives lost when one of the hijacked planes smashed into the Pentagon.

CHIEF MASTER SGT.

AMY MILLER, U.S. Air Force: President Joe Biden.

LAURA BARRON-LOPEZ: En route back to Washington from Vietnam, President Biden stopped in Anchorage, Alaska, to mark the solemn anniversary with U.S. troops and their families.

JOE BIDEN: The soul of America is the fortitude we found in the fear of that terrible September day, the purpose we found in our pain, the light we found in our darkest hour, an hour when terrorists believed they could bring us to our knees, bend our will, break our resolve.

But they were wrong.

They were dead wrong.

LAURA BARRON-LOPEZ: And in Shanksville, Pennsylvania, a memorial service where another hijacked jet crashed after passengers tried to storm the cockpit.

For the "PBS NewsHour," I'm Laura Barron-Lopez.

AMNA NAWAZ: Officials in New York recently identified two more victims from the attack at Ground Zero.

But remains of 1,100 other victims at the site have never been identified.

Iran and the U.S. moved one step closer to a long-awaited prisoner swap.

The Associated Press reports the Biden administration has approved letting international banks transfer $6 billion in frozen Iranian funds from South Korea to Qatar.

The money is to pay for humanitarian goods.

That could clear the way for Iran to release five American prisoners, while the U.S. frees five Iranians.

North Korean leader Kim Jong-un is headed to Russia tonight for talks with President Vladimir Putin.

Both countries have confirmed the trip, and a train similar to Kim's was spotted today approaching North Korea's border with Russia.

The meeting could come in Vladivostok, with Putin trying to obtain weapons for the war in Ukraine.

U.S. officials said it shows he is desperate.

MATTHEW MILLER, State Department Spokesman: I think there's no better evidence of that than now, a year-and-a-half later, not only has he failed to achieve his goals on the battlefield, but you see him traveling across his own country, hat in hand to beg Kim Jong-un for military assistance.

AMNA NAWAZ: In return for weapons, pressure could supply North Korea with energy and food aid, plus advanced technology for its missiles, submarines and satellites.

Ukraine's military says it has recaptured several oil platforms in the Black Sea near Russian-occupied Crimea.

Government video today showed troops approaching a rig and later hauling away military equipment.

At one point, they also fired machine guns at a Russian jet overhead.

Kyiv says the Russians had been using the platforms as military outposts.

Hurricane Lee is still churning in the open ocean tonight north of the Caribbean.

The storm is slowly moving northwest, but it's not expected to make landfall anywhere soon, and whether it veers towards the U.S. and Canada is unclear.

In the meantime, Arizona may finally get a break from extreme heat.

Phoenix has had 55 days this year of temperatures over 110 degrees, but readings are expected to drop slightly this week.

The Food and Drug Administration today approved new boosters for COVID-19 vaccines by Pfizer and Moderna.

They're aimed at curbing the latest variants, and they're cleared for adults and children as young as 6 months.

The CDC is expected to approve the shots tomorrow, and they could be available later this week.

Former President Donald Trump's lawyers are asking the federal judge presiding over his election subversion case in Washington, D.C., to recuse herself.

A motion filed today says her past public statements about Mr. Trump and his connection to the January 6 Capitol right call into question whether she can be fair.

On Wall Street, big tech stocks led the broader market higher, partly over enthusiasm about artificial intelligence.

The Dow Jones industrial average gained 87 points to close at 34663.

The Nasdaq rose 156 points, or 1 percent.

The S&P 500 added 30 points.

And the British scientist who pioneered cloning animals has died.

Ian Wilmut passed away Sunday in Scotland after a long illness.

His team gave the world Dolly the sheep in 1996, cloned from an adult sheep.

Dolly lived for six years.

Wilmut later focused on cloning human stem cells to help regenerate damaged tissue.

Ian Wilmut was 79 years old.

Still to come on the "NewsHour": Google heads to court for the first major monopoly trial in the modern Internet age; Tamara Keith and Amy Walter break down the latest political headlines; a new sound innovation promises to change how people experience music and movies; plus much more.

GEOFF BENNETT: President Joe Biden just wrapped a whirlwind trip to Asia, first to New Delhi, where he met with leaders of the world's most powerful economies at the G20 Summit, then an historic trip to Vietnam, his first ever.

Both visits are seen as a further push by the Biden administration to counter China's influence in Asia and the wider developing world.

In Hanoi, President Biden announced an increased partnership with Vietnam, a major relationship upgrade for the U.S., right on Beijing's on doorstep.

But while speaking to reporters, the president cautioned this deal is not about containing China.

JOE BIDEN, President of the United States: That's what this trip is all about.

Having India cooperate much more with the United States, be closer to the United States, Vietnam being closer to the United States, it's not about containing China.

It's about having a stable base, a stable base in the Indo-Pacific.

GEOFF BENNETT: To discuss the significance of President Biden's trip to Vietnam and what it means for Washington's Beijing policy, we welcome former U.S.

Ambassador to Vietnam Ted Osius.

He's now president and CEO of the U.S.-ASEAN Business Council.

Welcome back to the "NewsHour."

TED OSIUS, U.S.

Ambassador to Vietnam: Thank you very much.

Great to be here.

GEOFF BENNETT: This partnership between the U.S. and Vietnam appears to be a diplomatic win-win, coming at a time when Vietnam is trying to flex a degree of independence from Beijing and as the U.S., as we mentioned, is looking for friends across the Indo-Pacific region.

How do you view it, especially in light of the long relationship, the long, really tortured relationship between the U.S. and Hanoi?

TED OSIUS: Well, win-win is a good description of it.

The comprehensive partnership was established by President Truong Tan Sang and Barack Obama 10 years ago.

And what has just happened is a major milestone, in that President Biden and Nguyen Phu Trong, the general secretary of the Communist Party, upgraded that relationship by two rungs.

They made it a comprehensive strategic partnership.

In fact, it is comprehensive in nature and it's strategic already.

And I think both countries are going to benefit a great deal from deepening this partnership, from accelerating our collaboration.

GEOFF BENNETT: President Biden has made clear that his intention was not to start a cold war with China.

That's how he put it, but that the goal is to provide global stability by building U.S. relationships throughout Asia at a time of tensions with Beijing.

Practically, though, how will China view that?

Might they see this as a distinction without a difference?

TED OSIUS: Well, possibly.

There could be some blowback from China.

But if you look at the broader strategy that the Biden administration has adopted, they have created the Quad, a group of democracies.

They have created AUKUS, which strengthens our position and those of our allies in the region.

They have assembled a trilateral arrangement of Japan, Korea, and the United States.

They're working very hard to strengthen partnerships and alliances throughout the region.

Vietnam is not a traditional ally and probably never will be.

Neither is India, I would mention, where the president also visited.

But they're partners.

They're strong partners.

Indonesia is another strong partner.

Whenever we can strengthen these partnerships, friendships, alliances in the region, it's good for the United States.

And I would say that it's good for the entire region.

GEOFF BENNETT: To your point, in just the last five months, Biden has hosted the president of the Philippines at the White House.

He lavished the Indian prime minister with a state dinner.

He's hosted his counterparts the leaders of Japan and South Korea at that summit that was full of symbolism at Camp David.

What is the U.S. presenting as the mutual interest as he meets with these leaders?

TED OSIUS: Well, with all of them, economic engagement is very high on the list.

There are shared security interests as well, but they're looking beyond just traditional security concerns and looking at, how can we raise all boats?

How can we achieve greater prosperity and stability in the Indo-Pacific?

And so, to that point, what the president is saying is accurate.

It is not all about China.

Now, if you are Vietnam, you have China on your northern border, a 1,200-mile border with China.

You fought 22 wars against China.

It is a factor.

But Vietnam also wants a close relationship with the United States, because it's beneficial to its goals of achieving greater prosperity.

GEOFF BENNETT: Well, let's talk more about that, because is this approach by the administration, is it effective?

Because there are China watchers who will say that this idea of countering China's influence by building strategic alliances is inherently flawed, because these countries won't want to give up their relationships with China in exchange for a relationship with the U.S. that might be more limited in scope and might not come with the same amount of resources and support.

TED OSIUS: They don't have to.

No one is asking them to give up their relationship with China.

In fact, Vietnam's number one trading partner is China.

We -- it's also trading with us.

Vietnam sends more exports to the United States than to any other country.

And Vietnam is America's eighth largest trading partner.

But no one is asking them to give up their relationship with China.

No one is asking the Indonesians to give up their relationship with China or the Indians.

It's to enhance the ties to the United States and to other nations now that are part of a big trade framework, the Indo-Pacific Economic Framework, that's under negotiation.

So the United States is offering enticements, showing up at important moments in the Indo-Pacific.

The administration has been very active in going to Southeast Asia, which I cover, but also very much engaged with the other countries you mentioned, India, Japan, Korea, and, of course, Australia, New Zealand.

And all of this is aimed at making sure that the 75 years of peace and stability that we have had in the Indo-Pacific, with a few exceptions, is maintained.

GEOFF BENNETT: That the U.S. and Vietnam have emerged as partners after one of the most brutal wars of the 20th century is in some ways nothing short of remarkable.

We have about less than a minute left.

But give us a sense of how we got here.

TED OSIUS: Well, a lot of people took a lot of risks.

What they did was, they built -- they showed respect to the Vietnamese, from the Americans.

The Americans showed respect.

The Vietnamese showed respect to the Americans, in terms of what was important to us.

And then they built trust.

And that's personal.

And then they started doing things together.

And, for the last 30 years, our two countries have been doing things together.

And now, in fact, we have moved beyond just doing things, U.S. and Vietnam, but we're doing important things together throughout the region and the world, dealing with global health challenges, dealing with environmental challenges, peacekeeping.

We are partners not only looking at each other and working together, but in the region and in the world.

GEOFF BENNETT: Ted Osius is the former U.S. ambassador to Vietnam.

He's now president and CEO of the U.S.-ASEAN Business Council.

Thanks for your time this evening.

TED OSIUS: Thank you.

Thanks very much.

AMNA NAWAZ: Four months after the 9/11 attacks, the first detainees arrived at a U.S. military facility in Guantanamo Bay, Cuba.

More than 20 years later, 30 men are still there.

There's also a new debate over potential plea deals for five detainees accused of key roles in 9/11, including the alleged architect, Khalid Sheikh Mohammed, complicating the decades-long effort to permanently shut down the prison.

Carol Rosenberg of The New York Times has covered the facility since it opened, and she joins me now.

Carol, thanks for joining us.

Good to see you.

CAROL ROSENBERG, The New York Times: Good to see you.

Thank you.

AMNA NAWAZ: So, 9/11 families were notified about a possible plea deal with the U.S. military with five detainees last month.

Hundreds of families and survivors and some first responders have now sent a letter to President Biden asking him to reject the deal.

In fact, a spokesman for the group, a man named Brett Eagleson, who lost his father on 9/11, said this to Politico.

He said: "A plea deal avoids a trial.

A plea deal avoids a public reckoning.

And that's the important issue.

We cannot have the greatest terrorist attack in the history of this country fade away with plea deals for the last remaining prisoners in Guantanamo."

So, Carol, just bring us up to speed.

Where do those negotiations over possible plea deals stand?

CAROL ROSENBERG: The negotiation table is open.

The prosecution is still offering for the - - at least four of the five defendants to plead guilty in exchange for at most life in prison.

What President Biden did recently is, he rejected some conditions Khalid Sheikh Mohammed and the other detainees had put on their pleading guilty.

They wanted torture treatment guarantees and to not be held in solitary confinement.

The president said he's not signing off on those, but the prosecution is still open to a plea deal.

And the reason why is, a trial is years away.

And as they, I think, explained in their letter, the plea deal would provide what they call judicial certainty, meaning a conviction that would not be subject to appeal.

It is true they would not get a year-or-more-long trial, a parade of witnesses, but there would be a mini-trial, in which the government would present the crimes, and the defendants would have to admit to the crimes that they say the government could prove against them.

So I think there's been a little bit of misunderstanding.

It wouldn't look like the trial of the century, but it would look like a fact-finding for a jury to decide whether to give them the full life in prison or less.

AMNA NAWAZ: Carol, at the same time, we know that not everybody feels that way about wanting to reject those plea deals.

In fact, a group of children who lost their parents and grandparents on 9/11 also sent a letter to President Biden earlier this year saying they want plea deals.

They think plea deals are the only way to get accountability and to get closure.

There's a young woman named Elizabeth Miller, who's 28 years old.

She lost her dad on 9/11.

And this is what she told NPR earlier this month: ELIZABETH MILLER, Daughter of September 11 Victim: My fear is that, if we don't pursue plea deals and if the Biden administration doesn't put their full support behind this, I am 28 years old turning 29.

I'm going to be doing this advocacy until I'm 50-plus years old.

AMNA NAWAZ: Carol, if there aren't plea deals, what does justice look like for the remaining detainees at Guantanamo Bay?

CAROL ROSENBERG: Well, certainly, for the 9/11 defendants, excruciating continuation of pretrial hearings in which there is evidentiary debate and witnesses over whether the confessions the prosecutors would like to use at trial were voluntary and admissible.

The defendants weren't taken straight to Guantanamo or straight to the United States for trial when they were arrested a year and two years after the 9/11 attacks.

They were sent to CIA black sites for three and four years.

And that period has complicated the pretrial effort.

The CIA doesn't want to give up all the information.

The defense lawyers are insisting on more details.

And a judge and possibly a jury is going to have to decide which of the evidence is untainted.

AMNA NAWAZ: Carol, you know these numbers better than anyone, but I will put them up for the benefit of our audience.

That population at Guantanamo Bay has dramatically come down from near 800 people since beginning back in 2002.

Each president has transferred folks out.

President Bush transferred out about 540, President Obama about 200.

President Trump transferred out one individual to prison in Saudi Arabia.

And President Biden has transferred six so far.

Help us understand briefly, if you can, just why is it so hard to transfer out these last remaining prisoners?

CAROL ROSENBERG: Well, certainly, about 15 of them, they're not willing to give up anyways.

The government, the intelligence agencies and the prosecutors want about 15 of them, 12, 15 of them, continue to be detained as war prisoners.

The others are from countries we will not send them back to, Yemen primarily, because we think that they would become -- it would not -- Yemen does not provide the kind of rehabilitation and monitoring possibilities that this country insists on.

They need a third country to take them in and offer to monitor them, provide them resettlement and safe haven.

And, frankly, the Biden administration hasn't been able to seal the deal for more than a dozen Yemenis yet.

AMNA NAWAZ: Carol, nobody knows this story better than you.

No one's covered it more consistently than you.

As you know, folks have been saying for decades the facility needs to close.

I just wonder, as you look back on the last 22 years it's been open, how do you reflect on it, the fact that Guantanamo Bay prison is still open to this day?

CAROL ROSENBERG: The nation had a choice under Barack Obama to pick up Guantanamo and move the remnants of it to the United States or to continue to fund and run this remote, faraway prison down in Cuba.

And Congress prevented the closure that would have allowed some of these war prisoners to have been taken to the United States.

At this point, it's getting smaller and smaller.

The operation is getting smaller and smaller.

And it's very easy to forget that Guantanamo is there, which, in effect, means it's not as much a part of the national debate anymore.

AMNA NAWAZ: Carol Rosenberg of The New York Times, thank you, as always, for joining us.

We appreciate it.

CAROL ROSENBERG: Thank you.

GEOFF BENNETT: Starting tomorrow, the U.S. Justice Department's monopoly case against Google will go to trial for what's widely considered the biggest antitrust trial of the modern digital era.

Google is the undisputed giant when it comes to searching the Web.

More than 90 percent of searches start with Google.

The fundamental question in this trial centers on whether Google stifled competition and harmed consumers by becoming the default search engine through deals with phone makers and Internet browsers.

We're going to preview the key arguments in this case and take a look at what's at stake with two people who are closely watching it.

Cecilia Kang covers technology for The New York Times.

And Rebecca Allensworth specializes in antitrust.

She's also a professor at the Vanderbilt Law School.

Welcome to you both.

So, Cecilia, this is the biggest monopoly tech trial since the DOJ sued Microsoft some 20 years ago.

What's the issue?

CECILIA KANG, The New York Times: Well, at issue is whether Google, which is a monopoly in search, the Justice Department will assert, whether it actually maintained its monopoly through illegal means.

And the Justice Department will specifically argue that it did not keep its monopoly, did not cement its monopoly power through the great innovations of its search engine, but through these business deals that were exclusive contracts that made its search engine the default, effectively making it very, very difficult or impossible for any competitive search engines to thrive.

GEOFF BENNETT: And at stake in this trial, Rebecca, is a chance for the DOJ to prove that it can bring a successful anti-monopoly case in this modern digital era.

You have read the government's arguments to this point.

What's their case?

REBECCA ALLENSWORTH, Vanderbilt Law School: Their case is that Google is big, not just because it's great, but Google is big because they have cut off other avenues that their competitors would take to get in front of consumers, namely, by having exclusive dealing contracts or de facto exclusive dealing contracts.

That, under American antitrust law, could add up to a bad act, which is necessary in order to be found guilty of monopolization.

That's one element.

And the other element is just that you are a monopolist.

GEOFF BENNETT: And how has Google responded, Cecilia?

Because if they own 90 percent of the search traffic, it's hard for them to argue that they're not a monopoly.

CECILIA KANG: So, Google will focus on definitions of what the market is and what really is searched.

They're going to say, look, we are that bar that of you know on that blank page with the Google logo on it.

But there are so many ways that consumers search these days.

They search for retail items on Amazon.

They search for songs on Spotify.

They search for all kinds of -- they search for people and entertainment on TikTok.

They're going to argue that the definitions of what is search is much broader.

And they're going to argue that consumers like their products and that these contracts, very importantly, that they have struck with Apple, Firefox, Samsung and other companies to make their search engine the default are actually not exclusive, they're not complete blocks on consumers finding other search engines.

GEOFF BENNETT: Rebecca, Google, as you know, has already faced major fines over its competitive practices in Europe.

It also faces a separate challenge from the DOJ over its advertising technology business.

If Google loses this case, this search case, what's the practical impact?

REBECCA ALLENSWORTH: Well, there's impact on Google, for sure, but the impact I'm most interested in is on antitrust law.

This case most resembles the Microsoft case that the Department of Justice brought 20 years ago.

And I think the real critical question in this case is, has that case survived as a precedent, as a blueprint for bringing big tech to heel?

I think that companies like Meta and Amazon are going to be looking very closely at this case.

And so that matters to me a lot, the law.

As far as what it will matter to Google, the relief here, if the government wins, is not going to be fines, likely.

It's mostly going to be injunctive relief.

They're going to say, if these contracts violate the antitrust laws, you can't have contracts like this.

And I think that could open up some competitive space for other search engines to enter.

GEOFF BENNETT: Antitrust trials are long.

It's a long process.

And even if Google is found liable at this stage, there could be another separate proceeding to determine the best outcome in terms of resolving the case.

What are you watching for, Cecilia, as this case progresses?

CECILIA KANG: Well, I'm definitely watching to see whether the judge listens and accepts some of the arguments on a market definition and whether these contracts that Google had with these partners in business were indeed exclusionary and anti-competitive and, therefore, violations of antitrust law.

As far as what happens, the remedies, what's known as sort of the punishment that Google could face, it's early to say, but these kinds of cases and what the government actually tried to do with Microsoft two decades ago was pretty extreme.

It tried to seek a breakup of Microsoft.

Of course, that case settled and there was no breakup, but that is the potential.

There's potential that the government can ask that Google stop certain business practices.

And, in the most extreme version of remedies, it could ask for some sort of divestitures or breakup.

GEOFF BENNETT: Rebecca, there's the question of, why now?

Google's competitors have long accused it of brandishing its power to suppress competitors' links to travel, to maps, to reviews, that sort of thing.

There's been some regulatory investigations, but no major action at this level.

Why not?

REBECCA ALLENSWORTH: The answer to that question has two parts.

The first is that it's a different administration.

Now, of course, it started with the Trump administration in 2020.

But another part of the answer is that this behavior kind of all adds up.

And this is another thing I'm watching for in this trial.

The judge said in his decision this summer that: I don't have to look at everything all together.

I can look at each thing individually and say, does that violate the antitrust laws?

And I think that that's not quite the right way of looking at it.

And I'm curious what he means, because, certainly, part of the conduct that's disputed here is the sum of its parts.

It's all the things it's been doing over the last 10 years.

GEOFF BENNETT: Cecilia, what's your assessment?

Are we in a new era of antitrust enforcement?

CECILIA KANG: Well, absolutely.

In terms of the regulatory approach that this administration and the past administration has taken, as well as what we're seeing wind through the courts with these lawsuits, and this one that's the first to go to trial, we're seeing a real focus on weakening the grip of big tech on the economy and certain sectors of the economy, especially on the Internet.

So, this is a new era.

What the result will be will have potentially vast consequences on innovation, on how much data these companies can collect, which is a key to their future in A.I.

and other new technologies.

So this is not just about the current marketplace, but this is very much about the future of technology as well.

GEOFF BENNETT: Cecilia Kang covers technology for The New York Times, and Rebecca Allensworth is a professor at Vanderbilt Law School.

My thanks to you both.

REBECCA ALLENSWORTH: Thank you.

AMNA NAWAZ: As President Biden returns from a trip abroad, he's facing new political headwinds at home.

Democratic voters are expressing concerns about his bid for a second term, and House Republicans are ramping up calls for an impeachment inquiry.

Here to discuss is our Politics Monday team.

That's Amy Walter of The Cook Political Report With Amy Walter and Tamara Keith of NPR.

Welcome to you both.

Great to see you.

TAMARA KEITH, National Public Radio: Good to see you.

AMNA NAWAZ: So we talk a lot about the Republican side of the 2024 race.

We're going to focus on the Democratic side today, and specifically how voters are looking at that race.

I know you both saw a couple of questions I want to put to you from a CNN poll last week.

The first one asked Americans, does President Biden have the stamina and sharpness to serve effectively as president?

Twenty-six percent said yes; 74 percent said no.

Among Democrats on that question, they are split 50/50.

Finally, when they ask people, who should Democrats nominate in 2024, 66 percent said someone other than Biden.

Meantime, at the same time these polls are coming out, Mr. Biden was heading overseas for the G20 and the Biden campaign released this ad.

ANNOUNCER: In the middle of a war zone, Joe Biden showed the world what America is made of.

That's the quiet strength of a true leader who doesn't back down to a dictator.

AMNA NAWAZ: Tam, when you talk to White House sources, supporters of Mr. Biden, what do they say about the polls and why that ad right now?

TAMARA KEITH: They're pretty dismissive of the polls, the ones who are paid to work for President Biden.

However, I did talk to David Axelrod, who's a former adviser to former President Obama.

And it was for a story I was working on about an adaptation that the Biden White House has made, but they're not talking about, which is that, more frequently than not, President Biden is taking a shorter, more stable set of stairs in and out of Air Force One, instead of the taller ceremonial stairs that presidents traditionally take.

So he has started, since he had a fall, taking these stairs more frequently, much more frequently.

So I talked to David Axelrod for that story.

And he said, if Joe Biden were 15 or 20 years younger, he would not have a worry at all about his reelection chances, because of his policy accomplishments and what he's done as president.

But he's 80 years old.

And so David Axelrod and many other Democrats you talk to have these concerns.

I will say about that ad, that was an ad where it was officially about foreign policy.

AMNA NAWAZ: Right.

TAMARA KEITH: But that was like the political version of a Built Ford Tough ad.

That was the White House message and the official line we're going to hear again and again is: Watch me.

That's Biden's message: Watch me.

AMNA NAWAZ: And you hear him say that again and again, right?

TAMARA KEITH: Yes.

And when he goes out and goes to a Pella (ph) dog yoga studio and does Pilates and rides his -- rides a spin bike, he makes sure you know about it.

AMNA NAWAZ: Yes.

AMY WALTER, The Cook Political Report: Yes.

AMNA NAWAZ: Amy, who is that ad for?

Who are they talking to right now?

AMY WALTER: Well, a lot of it is talking to Democrats, which this is the point in the campaign where you're the incumbent president.

You're making sure you're shoring up your base, and especially a base, as you pointed out in this polling, where 50 percent of your own voters say that they think that your age is an issue and have worries about this.

The other thing I thought was really telling in that poll was, who should Democrats nominate?

Sixty-six percent said somebody other than Biden.

AMNA NAWAZ: Yes.

AMY WALTER: But then when you ask the follow-up, like, OK, great, well, who would that be, nobody.

AMNA NAWAZ: Right.

Yes.

AMY WALTER: Nobody gets more than 3 or 3 percent in an open-ended question there, which goes to the challenge for anybody who thinks, well, maybe I should take on Joe Biden.

There's not a -- there's not somebody sitting and waiting in the wings that Democrats are super excited about.

What they do know is what they see.

And they see a man who's in his 80s, who walks slowly, who has the gait of somebody who's an older person, who in press conferences will sometimes go off-script.

That's what they see.

And you can't tell voters that they're not seeing what they see.

AMNA NAWAZ: Speaking of what voters see, our Judy Woodruff, who's been reporting as part of her Crossroads project, sat down and observed a focus group of Democratic voters in Pennsylvania.

Some of these same issues came up.

So just take a listen to what some of those voters had to say.

We will talk after this.

WOMAN: How many of you are concerned about Joe Biden's age?

Just you four?

You're good, you think?

LISA, Pennsylvania Democrat: It's tough.

And I'm not going to -- I will bring Trump up again.

Age-wise, they're up there.

But even though he's a bully, he doesn't falter.

He doesn't mumble.

He doesn't falter.

He doesn't fall off the steps.

I mean, Biden does.

So, for me, age is never a factor unless you physically can't do something or verbally can't get across what you want to say.

AMNA NAWAZ: So, to be clear there, she was making -- drawing the difference between former President Trump, who she was referring to as a bully, and President Biden.

But, Amy, what's your reaction to hearing that voter?

AMY WALTER: It's what we hear from pretty much any Democrat that you talk to, whether it's those -- even those who privately donors and higher-ups in the party are saying the same thing, which is, we're very concerned about this.

And I think, for so many of these voters, the next question is, OK, what will you do in November of 2024?

Does that mean that you won't support Joe Biden?

I sat in on a different set of Democratic voters earlier this summer who also were somewhat disaffected about Biden for different reasons, mostly his age.

And they said, well, a second Biden term would probably be status quo.

Not a lot is going to happen that is necessarily good, but nothing bad will happen.

So, to them, it very much feels like, I don't really have a choice, because, if we don't have Biden, then we have Trump.

And as long as Trump is in the picture, the existential threat is what is more important to them than Biden's age.

AMNA NAWAZ: Tam, which leads to this question of the enthusiasm gap, right?

TAMARA KEITH: Right.

AMNA NAWAZ: Economy remains the biggest issue overall for most voters.

But here's another clip I want to get your reaction to.

Here's another clip from that focus group of Democratic voters in Pennsylvania.

WOMAN: Raise your hand if you're glad Joe Biden's going to run in 2024.

So, Ebony, why aren't you glad that Joe Biden is running again?

EBONY, Pennsylvania Democrat: I feel like a lot of people who voted for Joe Biden, they felt like he was going to do a better job than Trump, and he really didn't do a better job.

So, now it's kind of confusing, whereas, like, we already know what he has done now, so we don't know if he's going to do anything to support the country, because we really haven't seen a lot of change.

AMNA NAWAZ: Tam, this goes to the point Amy was making, but there is a real lack of enthusiasm there.

What does the White House say about that?

TAMARA KEITH: What they say is that they need more time.

They need -- and I apologize.

My voice is giving out.

They need more time to tell the president's story, for his policies to take effect.

As David Axelrod talked about when I was interviewing him, he said, look, the president has done all of these things.

He's passed all of these bills, he's signed all of these bills.

The challenge, though, is that many of them haven't taken effect, things like lowering prescription drug prices, allowing Medicare to negotiate prescription drug prices.

That is a huge accomplishment.

And if it makes it through legal challenges, which are still outstanding, that would be a really big deal for a lot of people.

That would happen in 2026.

They have announced the drugs that they will negotiate on, but in terms of people actually feeling it, it's not there yet.

AMY WALTER: And same with infrastructure, the CHIPS act.

TAMARA KEITH: Yes.

AMNA NAWAZ: Yes.

AMY WALTER: Again, very popular, but people, when you ask them, what is their number one concern, it is cost of living.

It's day-to-day costs of groceries and things like that.

Obviously, inflation is still pinching a lot of voters.

I think the other thing, you can't disconnect worries about his age and concerns about the economy.

Why?

Because people know that, for the next four years, if he's president of the United States, and they don't feel like he is going to have either the mental or the physical or the stamina to do that job, well, then what happens to the economy, right?

So you can't separate the age question from the economy question, I don't think.

AMNA NAWAZ: And, Amy, how do the Republican threats to ramp up this impeachment inquiry, how do they factor into all of that?

AMY WALTER: Well, I think they probably help Joe Biden, actually, because it rallies the base.

More than anything else, we live in a world of negative partisanship, as we know.

You may not love the person who's leading your team, but you definitely dislike the other team.

So if they're attacking your person, you're going to rally around them.

It'll also likely help to raise some money.

And if you're one of the 18 Republicans -- remember, the House is up for grabs too this year.

If you're one of the 18 Republicans that sits in a Biden district, do you really want to go on record impeaching the person who won in your district, when you already are dealing with the difficulty it's likely to be if Trump is the nominee?

AMNA NAWAZ: Tam, I will give you the last word here in the last 30 seconds.

TAMARA KEITH: So, I interviewed Chris Christie, who's running for president on the Republican side.

You can add him to the chorus of people that Amy is talking about who say the evidence isn't there yet for impeachment.

And he says, sure, keep investigating, but calling an impeachment right now would be a mistake.

And so, that said, I'm not sure that the president, the White House actually wants to endure the trauma that is impeachment and also the muddying that could occur about the high road and the contrast between Trump and Biden.

AMNA NAWAZ: Tamara Keith and Amy Walter, thanks for breaking it all down with us.

Always good to see you both.

AMY WALTER: Good to see you.

TAMARA KEITH: Good to see you.

GEOFF BENNETT: Many of the major music streaming services are now offering new spatial music playlists with more immersive versions of some of your favorite music.

The new music format is called Dolby Atmos Music.

And some view it as important an innovation as the advent of stereo music recordings in the 1960s.

Special correspondent Mike Cerre reports for our arts and culture series, Canvas.

MIKE CERRE: From the people who surrounded you with sound effects and movie theaters comes a new music format that can move the sounds of different music instruments and vocals all around your living room, inside your car, and even inside the space between your ears.

JOHN COULING, Dolby Laboratories: I think it's one of the most significant innovations, if not the most significant innovation of the last few decades in terms of music experience.

MIKE CERRE: John Couling heads up the entertainment division of Dolby, the San Francisco-based audio technology company that developed the relatively new Dolby Atmos Music format, now being integrated into consumer electronics products and music streaming services.

Unlike stereo, which combines all the music into left and right audio channels, Dolby Atmos Music separates various instruments and vocals and moves them between and around the two channels.

So John, unfortunately the newscasts like the "PBS NewsHour," we don't use Dolby Atmos yet.

But, for the benefit of our viewers, we're going to have to kind of show them what we're hearing.

JOHN COULING: What we have here are products that you can buy.

They're available in a store today.

MIKE CERRE: OK, so we might be hearing the bass here, we may be hearing the trumpet, Miles Davis, there.

It'll be all around you.

JOHN COULING: Absolutely.

And by spreading out the sound, you get this greater experience, both of immersiveness, but also clarity.

MIKE CERRE: What's the difference if we are listening to this in traditional stereo with two speakers?

JOHN COULING: So when you have two speakers, you have to make all of the sound come from those two locations, a left and a right.

And in a record, there's a lot of sound going on.

Well, in Dolby Atmos, you have much more space.

So as you spread them out into different locations, it allows each of them to shine, more authentic, more detailed, greater clarity of sound.

MIKE CERRE: Unlike other major audio evolutions requiring many years for creators to adopt and consumers to access, most people who bought a new cellular phone, tablet, computer or TV in the past four years already have access to the Dolby Atmos Music technology.

Automobile companies are adding the new technology starting with their luxury models.

This Mercedes is equipped with 16 speakers throughout the car.

Lizzo, yes.

JOHN COULING: Yes.

This is a great record.

It was actually a Record of the Year of the Grammys.

It's in Dolby Atmos.

And what you get is, you get Lizzo at the front, but you get her backing vocals all around you.

You got this great beat.

There's a lot going on in this song and the car really shows it off.

MIKE CERRE: We don't even need Lizzo up there for "Carpool Karaoke."

(LAUGHTER) MIKE CERRE: Hollywood sound engineer Brad Wood converted his backyard garage and spare bedroom unit into one of the early Dolby Atmos Music studios during the COVID hiatus after hearing Elton John's "Rocket Man" for the first time in the new format.

BRAD WOOD, Sound Engineer: Those slide guitars, they take off from behind you and up and over your head like a rocket.

And I think it's a great example of a song and a lyric and recording matching a technology.

MIKE CERRE: After 40 years of first playing his own music, then recording and mixing music for bands, the art of producing music has taken on a whole new dimension and jump-started his new career, reversioning classic recordings, like Diana Ross' "I'm Coming Out."

BRAD WOOD: And you can see all the green and yellow blobs.

Those are actually called objects in Dolby Atmos, and those are audio tracks.

And some of them are stationary.

Some are moving and they're all overhead.

And this is the trombone solo.

You can see it spinning around above us in the height speakers.

MIKE CERRE: You don't have to be in a studio with multiple speakers to hear the different instruments moving around.

The effect can even be heard in your earbuds and headphones connected to any Dolby Atmos Music-capable device.

BRAD WOOD: There are times when I am literally, like, moving my head around with my AirPods in and turning to my right and hearing a singer or a guitar coming out of the right.

It's a different kind of technology, because you still only have just the two speaker elements in your ears.

MIKE CERRE: But, according to some critics, hearing sounds from different directions can be distracting.

Neuroscientists and musician Dr. Daniel Levitin believes it depends more on the nature of the sound and how the technology is used.

DR. DANIEL LEVITIN, Neurologist: If there was something outside of our field of vision, a sudden loud noise that's called the startle response, depending on the noise, we might jump.

We might turn around.

But if they have been there all along as part of the musical piece, just like a humming refrigerator coming from the other room, you habituate to them and they're not alarming.

MIKE CERRE: For the Walkman and iPod generation that traded sound quality for music convenience, the clarity of this new format can even be more pronounced.

Crank it up.

Crank it up.

And for those of us still hoarding our vinyl records for a richer sound than traditional digital and streaming formats it's like listening in to the "Dark Side of the Moon."

(CROSSTALK) BRAD WOOD: Hammond organ in the back.

MIKE CERRE: For the "PBS NewsHour," I'm Mike Cerre in Los Angeles.

AMNA NAWAZ: Hope Boykin and Terri Ayanna Wright bring together prose and dance.

Boykin is a choreographer and a writer, and Wright dances her interpretation.

Tonight, they share their Brief But Spectacular take on creating their own paths.

HOPE BOYKIN, Writer: As a choreographer and a writer, I have found that I would like to make my movement look less abstract.

So, I write text, give spoken word to really display and unpack what I'm feeling.

TERRI AYANNA WRIGHT, Dancer: And I think, as the dancer, it's my job to just bring all of that to life, to the best of my ability.

HOPE BOYKIN: I don't need to be like them, those, because my faith, my lane, my own is my, is my, is my own.

I made a piece called "Journey."

"Journey" takes you on a journey of what it's been like to walk down my own path.

And Terri's body is the vessel.

Terri is the artist that does the translation as you hear me speak.

TERRI AYANNA WRIGHT: The most significant part of performing "Journey" is how much I can relate to it not only as a performer, but as a woman.

It is my journey just as much as it is Hope's.

HOPE BOYKIN: To struggle to balance, to my own, to hold my own, to wait, to rest, to be still, and know.

It's a duet, really.

My voice and her body work together to explain that our path is our own, literally in this tempo of slowness, of thick quality to let you know that the way we move, the way we have been working has been tough.

But we can't compare our work to anyone else's work.

We can't compare our lives to anyone else's life.

It has been worth every single effort, mine and mine alone, this journey.

My journey is not yours.

Once we realize that our path is our own, our journey is our own, then we really can find true joy, true success, true understanding and meaning in the work that we do.

And it gives us ownership over that.

My name is Hope Boykin.

TERRI AYANNA WRIGHT: And I am Terri Ayanna Wright.

HOPE BOYKIN: And this is our Brief But Spectacular take on... HOPE BOYKIN AND TERRI AYANNA WRIGHT: ... creating our own path.

AMNA NAWAZ: And you can watch more Brief But Spectacular videos online at PBS.org/NewsHour/Brief.

GEOFF BENNETT: And join us again here tomorrow night for an in-depth look at what you need to know about the newest COVID booster that could become available by the end of this week.

And that is the "NewsHour" for tonight.

I'm Geoff Bennett.

AMNA NAWAZ: And I'm Amna Nawaz.

On behalf of the entire "NewsHour" team, thank you for joining us.
