President Donald Trump’s takeover of the Washington, D.C., police department will temporarily reduce the district’s autonomy. Trump can more easily take over the Metropolitan Police Department than he can suspend the district’s home rule because ending home rule requires congressional action.

Trump mentioned New York, Baltimore, and Oakland as other cities where he wants to put the police under federal control. “This will go further," he said.

Vowing to “liberate” Washington, Trump said he would put an end to “the days of ruthlessly killing, or hurting, innocent people.”
