Minneapolis, Minnesota - Former Minneapolis police officer Derek Chauvin is appealing his conviction and sentencing for the murder of George Floyd.

On Thursday, Chauvin filed an appeal on his own behalf, arguing that the district court "abused its discretion" and that countless mistakes were made by judge Peter A. Cahill and the prosecution during the trial.

The former police officer was found guilty of second-degree unintentional murder, third-degree murder and second-degree manslaughter on April 20. He was sentenced to 270 months, or two and a half years, in prison on June 25.

According to a court filing for the appeal, Chauvin plans to address 14 separate issues in his defense, including that the district court abused its discretion by denying the 46-year-old a venue change and his request for a new trial altogether, and by failing to make an "official record of the numerous sidebar conferences" that took place during the trial.

The filing also claims the district court "prejudicially erred" by allowing the state to present "cumulative evidence with respect to use of force," and that the state itself committed prejudicial prosecutorial misconduct.

In the state of Minnesota, those involved in felony cases have 90 days to file an appeal after the final judgement or sentencing has been given.

In an affidavit also filed Thursday, CNN reported that Chauvin claimed he has no money and so can't afford legal counsel.

According to Chauvin, the Minneapolis Police and Peace Officers Association – who had paid for his legal representation throughout the murder trial – told him they were no longer obligated to pay for an attorney after his conviction and sentencing.

Despite this, Chauvin is still being represented by Eric Nelson, his attorney from the murder trial, in a federal civil rights case which he pled not guilty to last week.
