The political world is focused on Pennsylvania tonight for the first and only debate in the race for the state's open U.S. Senate seat.
Democratic Lieutenant Governor John Fetterman will square off against Republican Mehmet Oz tonight in a race that has tightened in the polls and gotten much more personal.
Fetterman has faced repeated questions about his health since suffering a stroke earlier this year and his campaign has accused Oz of mocking Fetterman's current condition.
