The Arizona Republic newspaper also found social media posts from Logan and Cyber Ninjas that call into question their impartiality.
"The parallels between the statistical analysis of Venezuela and this year's election are astonishing," Logan wrote on Twitter in December, before deleting his account, according to the Republic.
In a statement issued to local press in Arizona, Dominion criticized Cyber Ninjas as a partisan audit.
“The firms selected to conduct this audit are beyond biased,” the statement said. “Publicly available information shows they are led by conspiracy theorists and QAnon supporters who have helped spread the Big Lie. Dominion supports all forensic audits conducted by independent, federally accredited Voting System Test Labs — but this is not that. Over a thousand independent audits and recounts have taken place across the country since Election Day, and they all demonstrated the accuracy and reliability of our voting systems.”
