The audit revealed a few significant hiccups, with four counties -- Floyd, Fayette, Walton and Douglas -- discovering votes that were not part of the original count. Mr. Trump carried Floyd, Fayette and Walton Counties; Mr. Biden won Douglas County.
On Thursday, Floyd County's Board of Elections voted unanimously to fire its chief election clerk, Robert Brady, according to Dr. Melanie Conrad, a board member. Mr. Brady was fired after officials found 2,600 ballots that were left uncounted before the county's initial certification of votes.
The newly discovered ballots ate into Mr. Biden's statewide lead, which stood at 14,156 votes when the audit began. But most of the state's 159 counties saw only minor changes in their tallies, with the updated vote totals differing by single digits.
The state must certify the election results by 5 p.m. on Friday. The Trump campaign then has two business days to request a formal recount because of Mr. Biden's narrow margin of victory. That would be conducted with high-speed scanners.
