George Floyd's convicted killer Derek Chauvin has asked for a new trial.

The convicted murderer, a former Minneapolis police officer, says his lawyers are contending "pervasive misconduct" in how the state prosecuted its case, NBC News reported Wednesday.

A jury found Chauvin guilty of murdering George Floyd.

Eric Nelson, Chauvin's lawyer, petitioned the court claiming Chauvin's constitutional rights were violated when Judge Peter Cahill refused to change the venue of the trial.

An "abuse of discretion" deprived the law enforcement veteran of a fair trial, his legal counsel said.

The filing contends the court failed to protect jurors from the publicity surrounding the trial, CBS News said.

"The court has already rejected many of these arguments and the State will oppose them," NBC quoted John Stiles, deputy chief of staff for Minnesota Attorney General Keith Ellison, as saying in a statement.

According to Chauvin's lawyers, the effect of the publicity had a "far-reach chilling effect" on the ability to secure expert witnesses and prevented the jury from deliberating fairly out of "intimidation."

The 12-member jury included four Black people, two people who identify themselves as multiracial and six white people. It took the jury around 10 hours over two days to arrive at a guilty verdict.

Chauvin, 45, is now awaiting sentencing, which could come as early as this month or sometime in June.

Meanwhile, Rachel Moran, University of St. Thomas law professor, said it was unlikely Chauvin's attorneys would succeed in overturning the decision.

"No. No. No. Guilty. Guilty. Guilty," Ben Crump, the civil rights lawyer who represents the Floyd family, said in remarks quoted by The Independent. Crump opposed the request for a new trial.
