The former mayor of New York City is being sued for having "manufactured and disseminated" a false conspiracy theory that the electoral vote-counting machines were rigged against Donald Trump.
The lawsuit, which was filed by Dominion Voting Systems, is the second high profile case to be filed against allies of the former president for making unfounded claims of electoral fraud, Forbes reports.
In the video below, Hilary Clinton appears to predict Donald Trump's reaction to the 2020 election:Giuliani is being sued by the company after they sent him two letters warning that legal action was "imminent".
The second letter, which was sent on January 10, warned: "There is nothing you can say or do at this point to undo the hundreds of millions of dollars in damage that you and your allies have caused Dominion."
The company's voting machines are at the heart of a far-right conspiracy theory that Dominion has dubbed "the Big Lie".
In their lawsuit, the company refers to over 50 allegedly defamatory statements made by Giuliani.
Dominion claims that the statements, which were made on his podcast, on social media, in appearances on Fox Business, and during the January 6 rally before the Capitol riots, caused "unprecedented reputational and financial harm, and its employees' lives have been put in danger."
The lawsuit alleges that Giuliani "enriche[d] himself by falsely claiming that Dominion fixed the election."
Dominion argues that this was the case because Giuliani did not make any allegations about the company's electoral machines in the post-election lawsuits made by the Trump campaign.
"As a lawyer, Rudy Giuliani is well aware that he can be sanctioned for making false claims in court. That's why he never mentioned Dominion in court and admitted in court that his case wasn't a fraud case," Dominion attorney Thomas Clare said in a statement.
"Instead, he peddled his lies about Dominion in the court of public opinion, in concert with reckless media outlets that knowingly gave him a global platform to spew baseless falsehoods and to undermine confidence in our democracy."
Forbes reports that Dominion has already sued former Trump attorney Sidney Powell for defamation and has sent over 150 more individuals and companies letters warning of potential litigation.
Dominion is asking for $1.3 billion in damages from Guliani - the same amount requested from Powell in its first lawsuit.
