Elon Musk reposted a video from conservative commentator Ben Shapiro on Tuesday calling for President Donald Trump to pardon the federal conviction of former Minneapolis officer Derek Chauvin in the killing of George Floyd.

In the video Musk shared, Shapiro said pardoning Chauvin for federal charges would be “incredibly controversial, but I think that it’s absolutely necessary.”

Chauvin is serving two concurrent prison sentences for federal and state convictions after he knelt on the neck of Floyd, a Black man, for nine and a half minutes. Floyd’s killing sparked massive protests locally and nationwide calling for police reform and bringing heightened awareness around police brutality against people of color.

Even if Trump pardoned Chauvin’s 20-year federal convictions for violating Floyd’s civil rights, the president cannot pardon or commute Chauvin’s state sentence, which is 22 and a half years.

Minnesota Attorney General Keith Ellison said in a statement to the Minnesota Star Tribune that Trump has no power to pardon Chauvin’s state conviction, and that Chauvin would not walk free. He wrote that Chauvin “murdered George Floyd in front of the whole world.”

“The only conceivable purpose would be to express yet more disrespect for George Floyd and more disrespect for the rule of law,” Ellison said.

Department of Corrections Commissioner Paul Schnell said that if Chauvin was pardoned federally he would be returned to state custody to serve the remainder of his state sentence.
