Derek Chauvin's lawyer filed a motion on Tuesday in Hennepin County, Minnesota, for a new trial on grounds including jury misconduct and the state's failure to "adequately prepare its witnesses."

Why it matters: Chauvin was found guilty of murder and manslaughter last month. He killed George Floyd last year after kneeling on his neck for more than nine minutes.

• A photo of one of the jurors who convicted the former Minneapolis police officer has raised questions about his impartiality during the trial, and about whether the verdict could be overturned in an appeal.
• Defense attorney Mike Padden told the Minneapolis-based Star Tribune it is "disconcerting" that 31-year-old juror Brandon Mitchell did not divulge that he attended the anniversary of the March on Washington last summer, adding he may have been removed from the jury pool had he done so.

What they're saying: "The State committed pervasive, prejudicial prosecutorial misconduct, which deprived Mr. Chauvin of his constitutional rights to due process and a fair trial, including but not limited to: disparaging the Defense; improper vouching; and failing to adequately prepare its witnesses," the motion reads.
