Court filings revealed that President Trump is seeking to end the New York toll program within weeks. Legal experts say the deadline is not enforceable.

New York City must end its congestion pricing program by March 21, the Trump administration said in a letter made public on Wednesday. Last week, the Transportation Department said it was rescinding federal approval of New York City's congestion pricing program designed to reduce traffic and raise money to upgrade aging subway and bus systems.

The Federal Highway Administration said the Metropolitan Transportation Authority must stop collecting tolls by that date to allow for an "orderly cessation."
