President Donald Trump is promising new steps to tackle homelessness and crime in Washington. That's leading the city’s Democratic mayor to voice concerns about the potential use of the National Guard to patrol the streets in the nation’s capital.

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.

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