A supporter of Donald Trump paid the president's Rudy Giuliani $ 500,000 on behalf of a company co-founded

The payment attracted attention because of Parnas' role in helping Giuliani investigate former U.S. Vice President Biden, a contender for the Democratic presidential nomination in the 2020 election, and his son, Hunter Biden, who was a director of Ukrainian energy company Burisma

Charles Gucciardo paid the money to Giuliani Partners LLC on behalf of Fraud Guarantee

"Mr. Gucciardo invested because he believed that Mr. Giuliani - the former Mayor of New York City; former United States Attorney for the Southern District of New York; and the first name in cybersecurity - was in front of, behind and alongside the company," Zelin said, adding that his client's politics are irrelevant

Federal prosecutors are examining Giuliani's interactions with Parnas and another associate, a law enforcement source told Reuters last month
