Trump's plan to address crime in D.C. calls for deploying National Guard troops along the National Mall overnight Wednesday into Thursday morning, according to a source.

The influx came the morning after the Republican president announced he would be activating the guard members and taking over the District’s police department, something the law allows him to do temporarily.

A senior Army official said that some troops were deploying with D.C. police Tuesday night and that their mobilization marked the beginning of the deployment of 800 National Guard members.
