Dominion Voting Systems is suing Rudy Giuliani for $1.3 billion, claiming Donald Trump’s former personal lawyer carried out a “viral disinformation campaign” against the company by spreading lies on, Twitter, Fox News, and his podcast. Giuliani led Trump’s effort to get the November election result overturned, and increasingly embraced baseless conspiracy theories in order to do so. Central to his effort were numerous conspiracy theories about Dominion and its employees—rumors that first emerged from the QAnon fever swamp before being embraced by Trump and his team. In late December, Dominion sent Giuliani a letter warning that the company was keeping a record of all statements by the former New York City mayor. But Giuliani ignored the warning, and continued to disparage the company.
