Trump laid groundwork to call the results of the election in Nevada and elsewhere into question by saying that there was no possibility that he was tied with former Vice President Joe Biden. The most recent presidential poll of voters in the Silver State, a New York Times/Siena College survey released Saturday, showed Biden 4 points ahead of Trump but within the margin of error, a statistical tie.

“And then you read these fake reporters and they say, ‘President Trump is tied in Nevada.’ Tied. I don’t think so,” Trump said. “The only way we’re tied is if they screw around with the ballots, which they will do in my opinion. Okay? We’re not tied anywhere.”

Trump also falsely said that ballots in Nevada don’t need to have a valid signature, when in reality mail-in ballots will be rejected if the signature on it does not match the voter’s signature in their voter file. About 6,700 ballots were not counted in Nevada’s mostly mail-in primary election in June because officials could not match the signatures on the ballots.

“You don’t have to have an authorized signature on a ballot? No. They’re trying to rig an election and we can’t let that happen,” Trump said. “I hope you’re all going to be poll watchers, I hope you are.”
