Trump has warned supporters that the election is not being conducted fairly, telling a crowd in New Hampshire Saturday, "Remember, it's a rigged system. It's a rigged election. We're gonna beat the rigged system. We're gonna beat the rigged election."
"Our democracy relies on confidence in election results, and the speaker is fully confident the states will carry out this election with integrity," Ryan's national press secretary AshLee Strong told ABC News on Saturday.
Kaine also addressed recent sexual-assault accusations against Trump, telling Raddatz the Clinton campaign has absolutely nothing to do with the women coming forward.
Trump has vehemently denied the allegations of assault and threatened legal action against The New York Times for a story giving the accounts of two women making accusations against him.
At a rally in North Carolina on Friday he commented on one of the women -- it was not clear which -- who has made accusations: "When you looked at that horrible woman last night, you said I don't think so. I don’t think so."
The GOP nominee also told a crowd of young people at an event in Ohio that, "The Clintons and the corporate media are one in the same ... They collaborate and conspire together,” the Los Angeles Times reported.
Kaine said, "It’s not because of our campaign, but it’s very characteristic of Donald Trump that now he’s blaming these women."
"He’s making weird claims that, no, I couldn’t have assaulted this person, she’s not attractive enough to assault," Kaine said. "How bizarre is that?"
