The Riders Alliance, a longtime supporter of New York City’s congestion pricing program, vowed to defend the tolling plan after the Trump administration moved to revoke federal approval.

Daniel Pearlstein, policy and communications director for the group, said he expects the program will survive legal challenges.

“The program was approved under law from the first Bush administration. During the second Bush administration, the federal government actually tried to pay New York $354 million to start a congestion relief program, just like the one we have now,” Pearlstein said Thursday in a “Mornings On 1” interview.  “So clearly, it's founded deeply in our state and federal laws, and we enthusiastically expect that we will prevail.”

He added that the tolling program had already shown success in its first six weeks.

“Congestion pricing is a clear and obvious winner from the start. That's why it has the support of two out of every three drivers who pay the toll regularly,” he said, referencing the results of a poll conducted by the Partnership for New York City. “They're getting back valuable time.”

Gov. Kathy Hochul, who had previously taken a measured approach to congestion pricing, exhibited a more forceful stance Wednesday, with Pearlstein noting her shift reflects what many others have experienced.

“You are seeing in the governor… the zeal of the convert. People who had their doubts. Everyone has the story. Somebody had their doubts. They saw it up close. They saw it working,” he said. “They are saving New Yorkers and people from New Jersey valuable time every single day. Who would want to rip that away?”
