President Donald Trump's administration has given New York City a deadline of March 21 to end the congestion pricing program begun last month, a policy that was intended to reduce traffic in Manhattan's central business district and raise money to upgrade aging subway and bus systems.

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.

Duffy did not give a time frame for trying to shut down congestion pricing, saying only that federal officials would contact the state to "discuss the orderly cessation of toll operations." MTA CEO Janno Lieber said tolling would "continue notwithstanding this baseless effort to snatch those benefits away."
