Dr. Kevin O’Connor, who was former President Joe Biden‘s physician, is a key figure in the House Oversight Committee‘s investigation into White House aides’ alleged cover-up of Biden’s health. O’Connor was scheduled to appear for a deposition on Wednesday before the committee to answer questions about Biden’s health in office.

Former President Joe Biden’s physician has asked to delay his testimony before the House oversight committee this week, citing the need for an agreement that will respect doctor-patient confidentiality rules as part of the investigation into Biden's health in office.
