 The White House has released a letter from President Biden's doctor after a contentious press briefing on Monday over visits to the White House by a Parkinson's disease specialist. Secretary Karine Jean-Pierre told reporters the president isn't being treated for Parkinson's disease but couldn't reveal much more information. Monday night, the White House put out a memo from presidential physician Dr. Kevin O'Connor saying there were no findings which would be consistent with any cerebral or other central neurological disorder such as stroke, multiple sclerosis, or Parkinson's.
