Former President Joe Biden’s physician has requested to delay his testimony to the House oversight committee. An attorney for Dr. Kevin O’Connor argued in a letter that lawmakers must protect physician-patient privilege as part of the process. A spokesperson for the oversight panel said O’Connor could not disregard a congressional subpoena and that the committee would observe the House’s guidance on privileged statements on a case-by-case basis. The back-and-forth on O’Connor’s testimony is part of a broader debate over the scope of House Republicans’ inquiry into Biden’s mental state during his time in office.
