Chicago Police Department Superintendent Eddie Johnson is moving to fire a group of officers accused of lying about what happened in the fatal shooting of Laquan McDonald by Officer Jason Van Dyke.

In a letter drafted and made public early Thursday, Johnson is seeking to fire seven of the 10 officers who City Inspector General Joe Ferguson had recommended for termination.

Johnson, who has already stripped the officers of their powers, will submit his recommendations to the Chicago Police Board, which will make the final decision.

Johnson did not name any of the officers he is seeking to fire, but many of them were the patrol officers at the scene of the shooting, according to the Chicago Tribune.

A judge forced the release of the video of McDonald's shooting late last year after Mayor Rahm Emanuel's office fought hard against it. In the video, Van Dyke shoots McDonald repeatedly after he was already laying motionless on the ground from being shot.

The fallout from the video has been widespread in the department. Antony Wojcik, a lieutenant involved in the department's response to the shooting, retired in May. Deputy Chief David McNaughton, who ruled Van Dyke's shooting was justified, announced his retirement this week.

Van Dyke, who has been suspended without pay, was charged with murder and is awaiting trial.

The Chicago Police Department is under investigation by the Justice Department.
