After eight days of protests in the District over the death of George Floyd in police custody in Minneapolis, protests were underway Saturday as officials are preparing for the week’s biggest demonstration in Washington. Tens of thousands of protesters are expected in an all-out rebuke of aggressive police tactics, racism and the Trump administration’s militant approach to days of unrest that have gripped cities across the country.

Here are some significant developments:

• Several protests were taking place Saturday afternoon in Washington, including along K Street NW, near the White House, the U.S. Capitol and the Lincoln Memorial. Nearly a dozen different demonstrations run by as many organizations or individuals have been advertised for Saturday. Unlike many other large-scale demonstrations that the District hosts, no one person or organization is leading Saturday’s events.

• Though D.C. police and the National Park Service are preparing for tens of thousands of demonstrators, no one can say exactly how many to expect. Typical mechanisms used to gauge crowd size have been suspended or scaled back because of the coronavirus pandemic. The Park Service has stopped issuing protest permits.

• D.C. police began to prohibit vehicle traffic in much of downtown Washington at 6 a.m. Saturday in preparation for thousands of protesters expected to descend on the area. The closure is roughly between L Street NW to Independence Avenue SW. The western boundary is roughly along 19th Street NW, while the eastern boundary is roughly along Ninth Street NW downtown and Third Street NW along the Mall.
