Maryland's State Board of Elections said no fake mail-in ballots were distributed, directly rejecting President Trump's claim that 500,000 fraudulent ballots had been "revealed."
More than 500,000 voters requested mail ballots, but the board said the real problem was a vendor error that sent some voters the wrong party ballot before May 14.
Because officials cannot isolate every affected voter, Maryland will reissue ballots to all impacted mail voters, while online print-at-home ballots are not affected and voters will be notified.
Jared DeMarinis, the state elections administrator, said Trump's wording was misleading and that the replacement process removes doubt about the integrity of mail voting ahead of Maryland's June 23 primary.
Trump used the episode to press for the Save America Act, a House bill introduced in January that would require proof of citizenship and photo ID for voting.
Beyond replacing ballots, how can states prevent private vendor mistakes from undermining election integrity?
