Some 100 National Guardsmen will be in Washington this week to help support police officers patrolling protests planned by President Donald Trump supporters this week.

“We have received confirmation that the D.C. National Guard will be assisting the Metropolitan Police Department, beginning tomorrow through the life cycle of this event,” Metropolitan Police Chief Robert Contee III told reporters at a press conference on Monday.

National Guard personnel will be assisting police officers with crowd management and traffic control, freeing officers “to focus on anyone who’s intent on instigating, agitating, or participating in violence in our city,” he added.
