Derek Chauvin wants to go to federal prison, even though it means he'll do more time

After pleading guilty for his part in George Floyd's death, former police officer Derek Chauvin made one request: that he serve his time in federal prison.

Former Minneapolis police officer Derek Chauvin pleaded guilty to killing George Floyd in 2020 -- when he dug his knee into the back of the Black man's neck even though he was aware Floyd had lost consciousness and pulse. But in exchange for his plea, Chauvin, 45, made one request: that he be allowed to do his time in federal prison, even if it means he will serve a longer sentence.

Under the agreement Chauvin signed in U.S. District Court in St. Paul, Minnesota, on Wednesday, he must serve a minimum of 20 years in prison, and a maximum of 25.

While he was sentenced by Hennepin County Judge Peter Cahill to serve 22-and-a-half years in state prison, Chauvin could have been paroled in less than 15 years, assuming he accumulated all good-time credit, according to the federal agreement.

"The Floyd family understands Derek Chauvin may serve more time in federal prison than he would in state prison because federal guidelines indicate a greater percentage of a sentence is required to be served than at the state level. It is important to the family that he serves as much of his sentence as possible," the Floyd family's attorneys, Ben Crump, Antonio Romanucci and Jeff Storms, said in a statement to ABC News.
