The District’s officers will be empowered to share information with immigration authorities about people at traffic stops, per the order.

The order, amid Trump’s takeover of D.C. police, marks a significant departure for the force, though D.C. law still prohibits police from providing certain types of assistance.

The police chief of Washington, D.C., ordered an increase in cooperation between local officers and federal immigration agents on Thursday, a development that ramps up the stakes in an already tense environment after President Donald Trump’s security crackdown put the city’s police force under the command of the administration.
