 The White House has released a letter from President Biden's doctor after a contentious news briefing yesterday over visits to the White House by a Parkinson's disease specialist. After it was revealed that reporters found out that that specialist, Dr. Kevin O'Connor, had visited the White House eight times over the last eight months. But Dr. O'Connor said no findings which would be consistent with any brain or central neurological disorder such as stroke, multiple sclerosis or Parkinson's.
