The 2,600 uncounted ballots in Floyd County were mostly for President Donald Trump. The new discovery cuts Democratic presidential nominee Joe Biden's lead in the state by about 800 votes.
The ballots weren't counted because officials in the county did not upload them on Election Night, Gabriel Sterling, who manages the state's election system for Secretary of State Brad Raffensperger, told reporters during a virtual press conference.
"This is why you do the audits. There's no issues with any of the equipment or anything, they just didn't scan these ballots, it looks like, or the card was not put through properly," he said.
"So the secretary says this is such an amazing blunder."
