Attorney General Merrick Garland will announce Wednesday that the Justice Department is opening an investigation into the practices of the Minneapolis Police Department, Justice Department officials told NBC News.

The announcement will come the day after former Minneapolis police officer Derek Chauvin was convicted by a jury for the murder of George Floyd, an unarmed black man who was killed in custody last year.

The announcement, expected at 10 a.m. ET, was reported earlier by the Associated Press.

The Justice Department probe is known as a sample or exercise exam. The Justice Department had previously announced a separate investigation into whether Chauvin was violating Floyd’s civil rights.
