Voter fraud has been a major focus of disinformation campaigns this election season. The president has also been fixated on the issue, which has helped to legitimize false claims online.

Trump has claimed, for instance, that ballots have been tossed “in a river” and “in a wastepaper basket.” But the incidents he was referring to were not anywhere as sinister as he claimed: One referred to a load of mail that had been lost, then recovered, and included some ballots, while the other referred to a strange case of just nine ballots that seem to be related to a mix-up in envelopes. Trump’s claims have fed into existing disinformation narratives that are stoking fears of election fraud, such as false stories of thousands of ballots being dumped, or robocalls falsely telling voters that voting by mail is dangerous.

For their part, social media sites are ramping up efforts to fact-check, label and/or remove misleading content online during Election Day, but it’s a good reminder to be skeptical of sensational claims that might crop up as tensions run high in the final hours.
