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.

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