Mayor of Washington, D.C., Muriel Bowser announced on Sunday evening that she was imposing a citywide curfew from 11 p.m. to 6 a.m. Monday as the city braced for a third consecutive night of protests over the death of George Floyd.

In her tweet, the mayor also said that she was activating D.C. National Guard.

The announcement came as protests resumed in the capital after some violent clashes between protesters and police outside the White House, the night before.

In a video shared by Washington Post reporter Samantha Schmidt earlier that day protestors, many of whom were reportedly university students and teenagers, were marching down Georgia Avenue toward Lafayette Square near the White House. 

The unrest in the capital of the country triggered an angry response from President Trump, who at the beginning of the weekend drew intense backlash by warning that “when the looting starts, the shooting starts,” a phrase that had previously been used in the 1960s by a segregationist politician.

Trump was on a rampage again on Saturday during the protests in the capital, alleging Bowser refused to allow the city’s police department to help the Secret Service in controlling the demonstrators, he also threatened the use of “vicious dogs” and “ominous weapons” against the protesters.

“Great job last night at the White House by the U.S. @SecretService. They were not only totally professional but very cool,” Trump tweeted. “On the bad side, the D.C. Mayor, @MurielBowser, who is always looking for money & help, wouldn’t let D.C. Police get involved. ‘Not their job.’ ”

Bowser shot back, calling the President’s comments “gross” and dismissing him as a “scared man.”

The D.C. chapter of the ACLU condemned Bowser’s move on Sunday, accusing the mayor of stifling free speech.

“The nation’s capital is one of the most important places for the protest to take place right now,” Monica Hopkins, executive director of the ACLU of the District of Columbia, said in a statement. “Demonstrators are protesting police brutality, white supremacy, and state violence that claims Black lives. To impose a curfew is tone deaf and exactly the wrong approach.”
