The attorney general of Minnesota said Wednesday that the charge against the white former police officer who knelt on George Floyd's neck for eight minutes before the African American man died has been upgraded to second-degree murder.

"I want to begin with a reminder and that is that we're here today because George Floyd is not here. He should be here. He should be alive but he's not," Keith Ellison said at a press conference in St. Paul, the state capital.

"About nine days ago the world watched Floyd utter his very last words, 'I can't breathe,'" the attorney general said.
