Federal Justice Department will investigate whether the department has engaged in a pattern of unconstitutional policing.
This follows national outrage over the killing of Mr Floyd by Derek Chauvin.
The former officer was convicted of all charges on Tuesday, 20th April 2021.
Chauvin was seen in the video kneeling on Mr Floyd’s neck for more than nine minutes during an arrest in May 2020. Mr Floyd, an unarmed African American, was pronounced dead an hour later.
The footage sparked protests across the country, and calls for police reformation.
The murder that drove America to the brink
‘This is monumental. This is historic’
Mr Garland told reporters Tuesday’s verdict did not “address potentially systemic policing issues in Minneapolis”.
He said the investigation would “include a comprehensive review of the Minneapolis Police Department’s policies, training, supervision and use of force investigations”.
The attorney general added: “It will assess the effectiveness of the MPD’s current systems of accountability and whether other mechanisms are needed to ensure constitutional and lawful policing.”
