Pennsylvania’s Republican U.S. Senate candidate continues to question his opponent’s ability to do the job if he’s elected. Dr. Mehmet Oz says despite claims from John Fetterman’s campaign that his cognitive scores are normal, they haven’t released full cognitive testing results or information from a neurologist. Fetterman suffered a stroke days before the May primary and has had a light campaign schedule. Oz says that in an election year, voters should know whether candidates can fulfill their duties for their full term in office.
