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 deployment of the troops follows an order by US President Donald Trump for a crackdown on crime in the US capital, a similar action he took during protests in Los Angeles in June, prompting widespread backlash.

The 800 soldiers, in round-the-clock shifts of 100 to 200, will support Washington police and federal law enforcement officers.
