ABC News’ Martha Raddatz interviews Sen. Chris Van Hollen on “This Week" over President Trump deploying the National Guard to Washington, D.C.

President Donald Trump deployed 800 National Guard troops to the nation's capital as part of a crime crackdown in the city.

The Republican governors of West Virginia, South Carolina and Ohio announced Saturday they will send National Guard troops to Washington, DC, in an escalation of President Donald Trump’s efforts to federally take over law enforcement in the city.

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.

A National Guard deployment reacheed 400 members in Washington as a federal operation began targeting crime and homelessness around the clock Wednesday.

In New Mexico’s most populous city, National Guard troops are listening to the police dispatch calls, monitoring traffic cameras and helping to secure crime scene perimeters, tasks not usually part of the job.

P resident Donald Trump said on Wednesday that he will seek more permanent federal control of the Washington, D.C., police force as he continues his efforts to ramp-up crime enforcement in the nation's capital.
