During his second day of testimony on Capitol Hill, Secretary of State Marco Rubio said he hopes that the latest round of high-level political talks between Israel and Lebanon will result in a joint statement on ending hostilities. Israeli and Lebanese ambassadors to the U.S. are meeting at the State Department for a second day of negotiations.

The secretary of state finished nearly four hours of testimony before the House Foreign Affairs Committee, where he received praise from Republicans and sparred with Democrats over the Iran war, President Donald Trump's relationship with NATO and U.S. aid to Africa.

The hearing before lawmakers on Capitol Hill was the third of four in two days for the former Republican senator from Florida. The purpose of each hearing has been to discuss the State Department's budget. But they've often veered into discussions about the Trump administration's dealings with countries around the world.
Democrat shows Rubio videos of Trump with his eyes closed, says 'something is wrong'
California Rep. Ted Lieu displayed several clips of what he described as Trump sleeping while Rubio spoke during Cabinet meetings, saying they reflect concerns about the president's health. The short clips show Trump with his eyes closed on several instances during meetings from the last few months.
"I'm going to ask you to come clean with the American people and the White House as well: There's something wrong with Donald Trump's health or cognitive abilities," Lieu said.

In response, Rubio said, "I don't even know how to respond to that other than to tell you that it's absurd and ridiculous."
Rubio says Iran retains drone capabilities, but they're not as robust
Democratic Rep. Dina Titus of Nevada pushed Rubio to explain Iran's military capabilities. Trump and others claim American forces have decimated the Islamic Republic's military, and yet ships are still being attacked in the Strait of Hormuz, she said.
"So is the war still on or is the war off?" Titus asked.
Rubio acknowledged that Iran still has small boats with machine guns as well as some drone capabilities. But he said Iran lacks the ability to attack targets with swarms of drones as it once did.

Titus noted that the U.S. military has been using expensive weapons systems to take down the drones. Rubio said "that needs to change."
Rubio says Venezuela transition progressing well, but needs more time
Secretary of State Marco Rubio says Venezuela's transition to democracy is progressing but needs more time to consolidate and advance the reforms it has made since the U.S. ouster of former President Nicolas Maduro in early January.
In response to questions from lawmakers on the House Foreign Affairs Committee on Wednesday, Rubio stressed that it had only been five months since Maduro had been deposed and that conditions for free and fair elections – including the creation of independent media and political parties – are still works in progress. Rubio did say that Venezuela's oil revenue had increased significantly under U.S. supervision since January.
"It's not where it needs to be, but it is a long ways from where it was five months ago and poses not nearly the threat it once posed to America's national security. We're not satisfied with where it is, but we've come a long way," Rubio said.
Rubio says Greenland is part of Denmark 'for now'
Rubio made the "for now" statement when Democratic Rep. Sarah McBride of Delaware asked Rubio about Trump's calls for the U.S. to own the semiautonomous territory of Denmark to better defend the U.S.
Rubio said talks about the use of Greenland for collective defense are "in a good place," though he declined to publicly discuss the details.
McBride had asked Rubio if he shares Trump's belief that the U.S. needs to own land within NATO to defend it.
"The president's view is that it's a lot easier to defend it when you have control and complete control of it," Rubio said. "We are obviously having conversations with both Denmark and Greenland. They are ongoing on a monthly basis now. I think we'll have pretty good news."
Rubio says Trump still wants to be part of NATO, but alliance needs significant reform
Secretary of State Marco Rubio said the Trump administration has no intention of abandoning NATO but won't back down on demanding significant reforms.
Rubio told lawmakers Wednesday that the president plans to attend the annual NATO leaders' summit in Turkey next month, at which he will make the U.S. case for changes and again call for allies to increase their defense spending. The summit is to be held in Ankara on July 7-8.
"The president himself will be attending the next NATO, a meeting of heads of state where all of these points will be made clear. We're still in NATO, but NATO needs significant changes, and the president has made that clear," Rubio said.
Trump has been particularly irked by some NATO countries, mainly Spain, denying the use of airbases for the war against Iran.
Rubio insists to lawmakers that any U.S.-Iran deal will be 'better' than Obama agreement
Republicans and Democrats have raised concerns about the reported details of a deal between Tehran and Washington. And on Wednesday, Rep. Andy Barr, a Republican from Kentucky, questioned whether the deal was similar to the one former President Barack Obama made in 2015.
Rubio went on to outline the various issues being discussed and how they differ from the previous nuclear deal, which Trump withdrew from in 2018.
"Ultimately, any deal we do will be a good deal, or there won't be a deal, and it'll be better than JCPOA," Rubio said, referring to the Joint Comprehensive Plan of Action.
That agreement, which included Germany, France and Britain, had lifted most U.S. and international economic sanctions against Iran for restrictions on its nuclear program, making it impossible to produce a bomb and establishing rigorous inspections.
