Four congressional Democrats sent a letter to the owners of Dominion Voting Systems and cited several problems that “threaten the integrity of our elections,” including “vote switching.”

Dominion Voting Systems said in a statement on Friday that it "categorically denies" claims that its election software encountered glitches that impacted the results of the presidential election last week.

The company's software is used in 28 U.S. states, including in swing states like Arizona, Georgia, Michigan, Nevada, Pennsylvania and Wisconsin. After official sources called the national race for Joe Biden on November 7, President Donald Trump accused the company of deleting millions of votes cast for him across the country.

The internet was flooded with false claims about voter fraud in the days following the 2020 U.S. presidential election on Nov. 3, 2020. Many of these rumors centered around a piece of software from Dominion Voting Systems. We’ve addressed a few of these rumors in a previous article, but the most prevalent claim, and one that was spread by U.S. President Donald Trump himself on Nov. 12, 2020, was that Dominion software had deleted 2.7 million votes that had been cast for the incumbent.

There is no truth to this claim.
