WASHINGTON — National Guard troops began arriving at the D.C. Armory on Tuesday morning to report for duty to carry out President Donald Trump's directive to address crime in the nation's capital.

The presence of troops in the capital is expected to grow over the next week and the president is threatening to take similar tactics to other Democratic cities

Washington DC Mayor Muriel Bowser, a Democrat, who has denied crime is out of control in her city, described the troop deployment as an "authoritarian push". Trump, a Republican, has also threatened similar deployments against New York and Chicago, two other Democratic-controlled cities.
