The Louisiana National Guard, as directed by President Donald Trump, is going to Washington, D.C., to support the Metropolitan Police Department, the District of Columbia National Guard and D.C. local law enforcement.

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.

It was the first such action by the Guard since its deployment in Washington.
