Minneapolis Mayor Betsy Hodges has asked the U.S. Justice Department for a civil rights investigation into the Sunday shooting of Jamar Clark.
Hodges says a federal investigation will promote "transparency and community trust."
Some protesters had already been calling for a federal investigation, saying they didn't trust state law enforcement agencies to hold each other accountable.
The Minnesota Bureau of Criminal Apprehension is currently conducting the criminal investigation.
MPR's Cathy Wurzer spoke with Robert Driscoll, who served in the civil rights division of the Justice Department under President George W. Bush.
