The FBI has fired a group of agents who took part in a civil rights-related protest in Washington, D.C., in the wake of George Floyd's death in 2020, sources familiar with the matter told ABC News.

Many of the agents worked at the FBI's Washington Field Office at the time, and they were photographed in early June 2020 kneeling at the protest, the sources said.

At least some of them were reassigned earlier this year, but now as many as 20 agents have been fired, the sources added.

Sources pointed to an Associated Press photo showing some of the FBI agents at the protest kneeling.

The FBI declined to comment on the matter.
