The Trump administration is threatening to withhold or redirect federal funding to New York’s mass transit system if it doesn’t receive documentation of the steps taken to address crime and create a safe environment for riders and workers.

The Trump administration is threatening to withhold federal funding from the agency that runs the New York City subway if the Metropolitan Transportation Authority doesn’t comply with a request for information on transit crime.

There have been several high-profile and particularly brutal crimes on New York’s subway in recent years, including a woman getting set on fire, the killing of a homeless man, and a series of incidents in which people have been pushed in front of trains.
