The voting machine manufacturer is suing for defamation.

Before, during, and after the 2020 Presidential Election, lawyer Sidney Powell released numerous unproven theories about how the election was supposedly stolen from her employer, President Donald Trump. One of Powell’s most frequently repeated theories was that Dominion Voting Systems, the company that manufactures a large portion of the United States’ ballot counting machines, somehow rigged their machines to favor former Vice President Joe Biden. Powell has also asserted that Dominion bribed Georgia state officials for a no-bid contract, and that the company was working on behalf of Venezuelan President Hugo Chávez to steal the election (in spite of the fact that Hugo Chávez has been dead since 2013).

It seems Dominion has finally had enough of Powell’s slander, as today the company announced their intent to sue the lawyer for $1.3 billion on the grounds of defamation. This is the latest in a series of legal actions taken by Dominion and its employees; previously, an employee of Dominion that was harassed by Trump supporters, Eric Coomer, filed a private lawsuit against Powell and others. Dominion as a company has also sent numerous cease-and-desist letters to conservative media outlets like Fox News for pushing Powell’s conspiracy theories, which led to those outlets offering retractions.

Powell has not commented publicly on the lawsuit, nor has she responded to the many statements from federal and state officials refuting her theories. Election security experts have gone as far as saying that “in every case of which we are aware, these claims either have been unsubstantiated or are technically incoherent.”

Matt Masterson, a former senior election security adviser at the U.S. Cybersecurity and Infrastructure Security Agency, praised Dominion’s lawsuit, encouraging them to fight back against Powell’s theories.

“There’s no truth to any of the allegations about Dominion, and we know that because Georgia went back and counted all the ballots, and it was consistent,” Masterson said in a phone call to NBC News.

“The concern here is the court system was used as a vehicle for disinformation,” he added. “So I’m glad to see Dominion responding back, because this is the avenue they have.”
