One of the largest donations to Rudy Giuliani's legal defense fund is at the center of a new lawsuit that argues the $100,000 contribution rightfully belongs to victims of an alleged online fraud scheme. The donation by Matthew Martorano in September accounted for nearly 13% of all the money that Giuliani, the former attorney for Donald Trump and New York City mayor, raised in the fund. The fund was intended to help Giuliani pay for lawyers in the Georgia election interference case — where Trump is a co-defendant — and in a civil defamation case that Giuliani lost, brought by two Georgia election workers. But the plaintiff in the new civil suit — filed after CNBC reported on Martorano's donation earlier this year —claims that $100,000 flowed from Martorano's participation in an alleged online skincare product scam. They are seeking "to unwind" the donation to Giuliani. There is no public evidence that Giuliani and Martorano know each other. CN
