Georgia ballots rejected by machines were later altered by election workers to count.

A day after the November election, as Donald Trump and other Republican candidates clung to evaporating leads in Georgia, vote counters in Atlanta were confronted by a paper ballot known only by its anonymizing number 5150-232-18.

A Dominion Voting machine had rejected the ballot on election night because the voter had filled in boxes for both Trump and his Democratic opponent Joe Biden, an error known as an "overvote." The machine determined neither candidate should get a tally, and the ballot was referred for human review.
The image of the ballot, obtained by Just the News, shows the voter messily scribbled a large blob in the box to select Trump as president while also putting a thinner check mark next to Biden's name.  

At 6:10 p.m. ET on Nov. 4, 24 hours after the ballot was first scanned and rejected by Machine 5150, a panel of humans decided the vote should be awarded to Biden, with the notation "mark removed for Donald J. Trump.
