Mark Judge, who is said to have witnessed an alleged sexual assault by U.S. Supreme Court nominee Brett Kavanaugh decades ago, has retained Barbara “Biz” Van Gelder as his attorney as he denies ever witnessing the incident.

“I did not ask to be involved in this matter nor did anyone ask me to be involved. The only reason I am involved is because Dr. Christine Blasey Ford remembers me as the other person in the room during the alleged assault,” Judge, who was Kavanaugh’s friend and high school classmate at elite prep school Georgetown Prep, said in a letter to the Republican and Democratic heads of the Senate Judiciary Committee.
