88-year-old Estelle Bender, a Republican, said she wasn't the only person who was told incorrectly that they had already voted.

"The man next to me was arguing the same thing," said Bender, who was given a provisional ballot that she filled out and then "left really angry."

"I'd still like to know how I voted," Bender told KTLA.

In response to the reports, the Los Angeles County Registrar-Recorder said "The voters who experienced this issue were offered and provided a provisional ballot - the failsafe option to ensure no one is turned away from voting. Provisional ballots are regular ballots and once the eligibility of the voter is verified, they are processed and counted."
