President Biden, former President Obama and former President Trump are all headed to Pennsylvania this weekend.
Biden and Obama will campaign for Lieutenant Governor John Fetterman in Philadelphia tomorrow.
Polls show him in a virtual tie with Republican Mehmet Oz in the hotly contested U.S. Senate race.
Also on Saturday, Trump is set hold a rally at the Arnold Palmer airport east of Pittsburgh. Trump is hoping to boost the chances for GOP candidates he has endorsed.
