George Floyd family lawyer: Derek Chauvin should face first-degree murder charge

The lawyer for the family of George Floyd, whose death in police custody has sparked unrest across the US, has told CBS News' Face the Nation that it should be a case of first-degree murder.

Former Minneapolis police officer Derek Chauvin has been charged with third-degree murder, but lawyer Benjamin Crump said: "We believe he knew who George Floyd was."

He said the Floyd family was "notified by the owner of a club that Derek Chauvin was an off-duty police officer where George Floyd was a security guard, and so they had to overlap".
