MTA Chair and CEO Janno Lieber said Thursday he remains “optimistic” that New York City’s congestion pricing plan will move forward, one day after the Trump administration moved to rescind federal approval of the program.

"I'm optimistic that the traditions of bipartisanship on transportation and the way that the federal government has funded transportation through formulas…will prevail in the end," Lieber said on "Mornings On 1” as the MTA prepares to fight in federal court to save the program.

The legal battle comes after U.S. Department of Transportation Secretary Sean Duffy announced Wednesday his agency would rescind its previous signoff on the plan. The MTA responded by filing a lawsuit in federal court, arguing the move violated federal law and constitutional rights.

Lieber defended the MTA’s legal challenge, saying federal officials do not have the authority to unilaterally terminate the plan.

“We had a 50-page complaint ready to go, and we hit the button to file it about three minutes after the official release of Secretary Duffy's letter that purportedly terminated the program,” Lieber said. “It's not really even a close case. Under the federal program, what we did is exactly what the federal program says you can do.”

Lieber said he believes the administration’s decision will not hold up in court.

“There're all kinds of case law in federal courts about the procedures that the federal government has to use to take away an approval,” he said. “None of this complies with that, and that's why we are so comfortable that this is a strong case, and we're going to win.”

Lieber said the cameras for the tolling program will also remain on.

“They didn't even ask us to turn off the cameras right away. They said they wanted to talk about it. But more important, something of this kind cannot be taken away without a federal court order. We're going to fight it all the way,” Lieber said.

While acknowledging the potential for further financial retaliation from Trump, Lieber said he believes the president will eventually side with his hometown.

“Donald Trump is a New Yorker. He knows New York,” Lieber said. “I believe he will, in the end, putting this issue aside, have the wisdom not to try to go after New York again and again and again.”
