President Donald Trump announced Monday that he is federalizing the Washington, D.C., Metropolitan Police Department to address a “public safety emergency,” a move that will give him complete law enforcement control over the district.

The president announced on Monday the deployment of 800 National Guard troops in the nation’s capital and takeover of the D.C. Metropolitan Police Department.

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