The increased presence of law enforcement drew a crowd of protesters a day after the National Guard was deployed on city streets.

Steps away from a YMCA, popular bakery and local pharmacy, a group of law enforcement officers across several agencies turned a busy intersection in a mixed residential-commercial area of Washington, D.C., into a police checkpoint Wednesday night as part of President Donald Trump’s directive to crack down on crime in the nation’s capital.

Uniformed officers with the Metropolitan Police Department stood alongside Homeland Security Investigations personnel and several plainclothes agents at the checkpoint in the U Street corridor at one of the first checkpoints set up since Trump temporarily put D.C. police under federal control and deployed the National Guard.

More than 100 protesters soon gathered in the Northwest D.C. neighborhood, heckling law enforcement and chanting “get off our streets” as agents stopped cars and flagged some vehicles for additional investigation. Several protesters began warning drivers to avoid the checkpoint.
