The Justice Department on Thursday announced a lawsuit against New York City’s so-called sanctuary city policies, days after the Trump administration blamed those policies for the shooting of an off-duty US Customs and Border Protection officer in Manhattan.

The Trump administration filed a lawsuit against New York City on Thursday over its “sanctuary” laws, continuing a monthslong effort to crack down on localities that attempt to shield undocumented immigrants from federal detainment efforts.

The case filed Thursday is the latest attempt by the Trump administration to sanction New York City over its "sanctuary" policies. Earlier this year, the administration began to claw back tens of millions of dollars that had already been allocated by Congress in migrant-crisis reimbursements.
