The secretary of transportation, Sean Duffy, posted an unusual video that features interviews with five men who are opposed to New York’s tolling program.

The Trump administration said it revoked federal approval for the tolling plan on Feb. 19. New York leaders are fighting to keep it.

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.

The transportation secretary said he would revoke federal approval for the program, citing the cost to motorists; the Metropolitan Transportation Authority quickly filed a lawsuit to stop the move.

The program is the target of several lawsuits and of President-elect Donald J. Trump, who said he will end it permanently once he takes office on Jan. 20.

The tolling plan, the first of its kind in the country, started on a Sunday to work out the kinks before rush hour traffic Monday morning. It appeared to be running smoothly as drivers adjusted to the new fee.

After twists and turns, a contentious plan meant to reduce traffic and pay for transit improvements is scheduled to take effect at midnight Sunday.

The decision in a lawsuit brought by the State of New Jersey meant that the tolling plan could go ahead as planned, New York said. A lawyer for New Jersey disagreed.

Families in Washington Heights are being pushed out by rising rents and costs, and New York City is losing its youngest demographic group.

Manhattan’s new tolling program is still being challenged in federal and state courts, with rulings possible before it begins on Jan. 5.
