White House official says to expect "significantly higher National Guard presence” in Washington, D.C. Wednesday evening.

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.

Residents in one Washington, D.C., neighborhood lined up to protest the increased police presence after the White House said the number of National Guard troops in the nation’s capital would ramp up and federal officers would be on the streets around the clock.

President Trump is calling up the D.C. National Guard and federal law enforcement to address crime in the capital.

For a city whose population is 41% Black, D.C.’s homeless population is disproportionately Black, at 82.5%. Compare that to the city’s white population: 39.6%, with 6.6% homeless, according to the U.S. Census Bureau. Sixty percent of all homeless people are men.

President Donald Trump long had a playbook for deploying the National Guard in D.C. and a week ago had new motivation after a former aide was hurt in an attempted carjacking.
