President Trump sent shockwaves through the Tri-State and around the nation yesterday, comparing himself to a king as his administration moved to try and kill New York's congestion pricing program.

The move sparked outcry from top officials and public transit advocates across the Hudson.

But plenty of praise from New Jersey politicians who have rallied against the tolling scheme for months.

New York leaders are already fighting back in court and say they'll keep the cameras on until a judge tells them to stop.

Senior correspondent Brenda Flanagan reports.

Say the cameras are staying on.

We are keeping the cameras on.

New York Governor Kathy Hochul defiantly vowed to fight the Trump administration's order, yanking federal approval for congestion pricing.

Barely seven weeks after the all cameras turned on Jan. 5, a long time foe who considered it bad for business.

The president posted on ex congestion pricing is dead.

Manhattan and all of New York is saved.

Long live the King.

New York hasn't labored under a king in over 250 years.

We are not.

We sure as hell are not going to start now.

So think about this next time you're stuck in traffic.

Hochul and the MTA immediately sued to vacate the order across the river.

Governor Murphy welcomed Donald Trump's attack on the whole plan.

He had said publicly he was opposed to it.

So he's been following through.

Whether you like it or not.

On Inauguration Day, Murphy, in a letter it asked the president to rescind congestion pricing after a federal judge refused New Jersey's appeal to block it.

Murphy had argued this is one this was done purely to line the pockets of the MTA, that this this was a financial move far more than it was an environmental move.

And Transportation Secretary Sean Duffy echoed that, calling congestion pricing a slap in the face to commuters.

He mentioned Murphy twice in his memo to Governor Hochul ordering a phase out for congestion pricing, because the plan provides no toll free option for many drivers, and the toll rate primarily raises revenue to fund mass transit, not reduce traffic congestion.

In light of the president's concerns, as well as the concerns expressed by New Jersey Governor Murphy.

I've concluded that the scope of this pilot project, as approved, exceeds the authority authorized by Congress, Duffy wrote.

But they actually cited the will of New Jersey in New York.

New Jersey didn't want this.

Ignoring the will.

We will live here.

Their elected leaders in Albany.

And all of a sudden, the Trump administration is signing well.

New Jersey wasn't happy.

It might have been great for, as the MTA said, for parts of New York City, but not for northern New Jersey, not by the GW bridge, where we saw an increase of truck traffic.

Congressman Josh Gottheimer, a Democrat running for new Jersey governor, has long battled congestion pricing.

He called Trump's king post, quote, absurd, but celebrated the administration's action.

As for New York, did they want to keep these cameras on while they're fighting this after yesterday's decision?

They're going to have to reimburse, in my opinion, every single person they're charging, at least from Jersey, because people should get their money back.

New York's lawsuit cites statistics showing the toll is cutting traffic.

It challenges Duffy's order, arguing the Trump administration's action here is just the latest example of its disregard for the rule of law.

Defendants are not authorized by any law, statutory or constitutional, to unilaterally terminate the value pilot pricing program agreement.

Columbia law professor Michael Girard thinks that's a strong argument.

The agreement that the federal government signed with the MTA for congestion pricing gave only the MTA the power to stop it.

It didn't say that the federal government could stop it, and I don't think they can.

Other congestion pricing advocates also criticized the feds sudden flip flop on a program it greenlighted just last November, calling the move unprecedented and deeply political.

It's unfortunate that at this moment in time, when there are larger issues at hand, we are playing political games with a transportation program that has proven to work.

The federal case will wind its way through New York's famously independent Southern District, and Murphy and Hochul should have lots to discuss at the National Governors Conference starting today in Washington.
