President Donald Trump has spent days escalating his rhetoric on crime in Washington, calling the U.S. capital "totally out of control" and ordering a federal law enforcement surge ahead of a Monday press conference to outline a sweeping crackdown.

Trump says homeless people must go "far" from the nation's capital, as part of his anti-crime plan, but the mayor pushes back.

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