 The White House has released a letter from President Biden's doctor after a contentious press briefing Monday over visits to the White House by a Parkinson's disease specialist. Memo from presidential physician Dr. Kevin O'Connor said the visits from the neurological specialist were part of Biden's annual physicals and all the results have been made public. O'Connor also noted there were no findings which would be consistent with any cerebral or other central neurological disorders such as a stroke, multiple sclerosis or Parkinson's.
