Rittenhouse, 18, is charged with killing Joseph Rosenbaum, 36, and Anthony Huber, 26, and wounding Gaige Grosskreutz, 26, late on Aug. 25 during protests in Kenosha over the police shooting two days earlier of Jacob Blake, who was left paralyzed.
His lawyers say Rittenhouse acted in lawful self-defense, citing widely seen cellphone videos of the shootings.
Up until Friday, all of Rittenhouse's Wisconsin court appearances had been via Zoom, from his lawyer Mark Richards' office in Racine. He did appear in person in a Waukegan, Illinois, courtroom in October while fighting his extradition to Wisconsin. He had returned home to Antioch, Illinois, the night of the shootings before surrendering to police there.
