Donald Trump told supporters in Pennsylvania Friday night that the only way he could lose is if “they cheat.”

“She can’t beat what’s happening here,” Trump said of Democratic presidential nominee Hillary Clinton, speaking at a rally in Altoona.

“The only way they can beat it, in my opinion, and I mean this 100 percent, is if in certain sections of the state they cheat.”

He advised the crowd, “Go down to certain areas and watch and study and make sure other people don’t come in and vote five times.”

Trump currently trails Clinton by 9 points in Pennsylvania.
