Did a whistleblower claim that Dominion Voting Systems changed 3.8 million votes in the 2020 election?

There's no evidence to substantiate a post making the claim. The post did not identify the alleged whistleblower and did not offer any proof. Previous claims about purported vote flipping have been repeatedly disproven. A spokesperson for Dominion dismissed the latest allegation as a "recycled attempt to drum up false hope."

The claim said three people have now "come forward" but it did not name any of the three purported whistleblowers and did not offer any proof to substantiate its statement that 3.8 million votes were switched.

Independent experts and election officials have all, repeatedly, defended the integrity of the 2020 election, which has been described as the "most secure in American history."

Dominion has also dismissed allegations of fraud. It has a section on its website dedicated to addressing rumors and speaks to the specific allegation of vote switching.
