Joe Biden’s White House physician on Wednesday declined to answer questions during a closed-door deposition with the House Oversight Committee, invoking his Fifth Amendment right as the Republican-led panel pushes forward in its probe of the former president’s mental fitness and decline.

Dr. Kevin O'Connor, former President Joe Biden's physician, pleaded the Fifth during a brief appearance before the House Oversight Committee for a closed interview.

Kevin O’Connor cited both physician-patient privilege and his Fifth Amendment right against self-incrimination in refusing to answer questions from the House Oversight Committee.
