On Tuesday night, more than 1,450 federal law enforcement officers and National Guard members patrolled Washington, according to a White House official. Forces made 43 arrests on Tuesday night -- nearly twice the amount they made Monday night.

President Donald Trump directly controls DC's police and National Guard because of the federal enclave's unique status, experts say.

President Trump said he will seek cooperation from Republican lawmakers to extend deployment of National Guard troops in Washington, D.C. Such a move in Congress would likely need Democratic support.
