The trial began last week with jury selection. Two people who'd already been selected to serve on the panel were dismissed on Wednesday after they told the judge they'd learned about last week's $27 million settlement between the city of Minneapolis and Floyd's family.
Jury selection resumed on Thursday with a panel of nine already seated. Attorneys must settle on three more and two alternates before Chauvin's trial can begin in earnest.
Cahill said he will also rule whether evidence of Floyd's 2019 arrest can be included in the trial.
If he isn't acquitted, Chauvin -- who knelt on Floyd's neck for several minutes last May and caused his death during an arrest -- can be convicted of second-degree murder, third-degree murder or second-degree manslaughter.
Chauvin and two other officers involved in Floyd's arrest were later fired from the Minneapolis police force.
