Minnesota’s attorney general is pushing back on calls for President Trump to pardon Derek Chauvin, the white police officer convicted of murdering George Floyd in 2020. Speaking Thursday on CNN, Keith Ellison said such calls show a “blatant disrespect” for the law and for Floyd’s family.

The former cop was convicted in Minnesota of killing George Floyd and pleaded guilty to federal civil rights violations.

“The Ben Shapiro Show” host has launched a petition backing a public letter to Trump, 78, contending that Chauvin, now 48, was “unjustly convicted” of Floyd’s killing, which led to riots in cities across the US and a national reckoning on the issues of race and policing.
