National Guard troops pulled up in front of the Washington Monument on Aug. 12. They weren't armed then, but they could be soon, Army officials said.

The presence of National Guard troops in Washington, DC, is expected to expand Wednesday evening, according to a White House official, as President Donald Trump’s takeover of the city’s law enforcement continues to take shape.

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.
