Former Vice President Al Gore will campaign for Democrat Hillary Clinton today, while Republican Donald Trump continues to fight back.

FOX's Rachel Sutherland reports from Washington:

Campaigning in Pennsylvania, Trump asked supporters to keep a close eye on the polls so that the election is not stolen from them, saying he wants every vote counted "100 percent". The Republican also hinted he's expecting more negative headlines:

(Trump) "If they want to release more tapes saying inappropriate things, we'll continue to talk about Bill and Hillary Clinton doing inappropriate things."

Trump repeated his claims that the system is rigged and said that as election day approaches he'll make three to four stops a day and may squeeze in six stops a day in the final week of the campaign.
