The 107-page lawsuit, filed in the Federal District Court in Washington, accuses Mr. Giuliani of carrying out “a viral disinformation campaign about Dominion” made up of “demonstrably false” allegations, in part to enrich himself through legal fees and his podcast.

The suit seeks damages of more than $1.3 billion and is based on more than 50 statements Mr. Giuliani made at legislative hearings, on Twitter, on his podcast and in the conservative news media, where he spun a fictitious narrative of a plot by one of the biggest voting machine manufacturers in the country to flip votes to President Biden…

Laying out a timeline of Mr. Giuliani’s comments about Dominion on Twitter, his podcast and Fox News, the company notes that Mr. Giuliani avoided mentioning Dominion in court, where he could have faced legal ramifications for falsehoods. “Notably, not a single one of the three complaints signed and filed by Giuliani and other attorneys for the Trump Campaign in the Pennsylvania action contained any allegations about Dominion,” the lawsuit says.
