Around 2,100 Los Angeles County voters received faulty mail-in ballots that omitted the section that would allow them to vote for president. The ballots were distributed as part of Gov. Gavin Newsom's plan to send all 21 million registered voters in the state an absentee ballot for the November 3 election.
The L.A. County clerk's office issued an apology for the error, which it said only "impacted a very small number" of voters in the state.
"We are now in the process of alerting all affected voters in this precinct of the error by robocall and email, and, tomorrow morning, we will be mailing out new, corrected ballots with a letter describing the error," spokesperson Michael Sanchez said.
The Trump campaign has been warning for months that mail-in voting is unreliable and would potentially lead to more cases of fraud and disenfranchisement of voters.
However, many states have seen an increase in the distribution of absentee ballots primarily out of voter concern over potential COVID-19 exposure at in-person polling locations.
