 The White House late tonight released a letter from President Biden's doctor seeking to clear up why a neurologist with an expert in Parkinson's disease had visited the White House several times. It turns out that the president has not had a neurological exam outside of his annual physicals, but other people in the White House, according to the president's doctor, were getting checkups by this neurologist. So that clears up a bone of contention from earlier today. Karine Jean-Pierre,
