Voting software deployed by the election hardware company Dominion Voting Systems can allow election staffers to manually adjust tally amounts while reviewing scanned ballot images, a process that the company says allows for "resolution of voter intent" in cases where ballot marks are unclear.
Dominion has been at the center of tumultuous controversy since the election amid reports of glitchy and/or unreliable voting software and hardware. The company has a presence in a majority of U.S. states, including critical battleground states in which Democratic challenger Joe Biden has been declared the winner by major media outlets.
President Trump has suggested that malfeasance by Dominion is responsible for the narrow edge in posted vote totals that Biden holds in those states. Dominion, meanwhile, has unequivocally denied any wrongdoing or errors within its machines.
"No credible reports or evidence of any software issues exist," the company has stated on its website. "Dominion equipment is used by county and state officials to tabulate ballots. Human errors related to reporting tabulated results have arisen in a few counties, including some using Dominion equipment, but appropriate procedural actions have been taken by the county to address these errors were made prior to the canvass process."
