 Another public relations problem for the Biden campaign. The White House faces repeated questions about President Biden's medical history. It released a letter from Biden's doctor last night after Press Secretary Karine Jean-Pierre struggled to answer direct questions about Biden's health and whether visits to the White House by a Parkinson's disease specialist involved the president. Has the president been treated for Parkinson's? No. Is he being treated for Parkinson's? No, he's not. Is he taking medication for Parkinson's? No.
