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.

Trump in a social media post on Sunday declared that "the Homeless" in Washington, D.C., will "have to move out."

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