Giuliani told Reuters that Fraud Guarantee, Lev Parnas’s Boca Raton, Fla.-based company, took on Giuliani Partners as a management and security consulting firm around August 2018. Giuliani was hired to consult with the company and provide legal advice.

Giuliani also said he received two payments within weeks of each other but did not say when they were made.

Parnas, a Ukraine-born businessman, was one of two Giuliani associates  who helped the former New York City mayor in efforts to investigate former Vice President Joe BidenJoe BidenSupport drops for Medicare for All but increases for public option Bolton told ex-Trump aide to call White House lawyers about Ukraine pressure campaign: report Federal prosecutors in New York examining Giuliani business dealings with Ukraine: report MORE. House Democrats launched an impeachment inquiry after revelations that Trump pressured his Ukrainian counterpart to investigate Biden, a leading Democratic presidential candidate, and his son.

The latest development comes after The New York Times noted last week that Parnas told associates he paid Giuliani hundreds of thousands of dollars for his work.

Parnas and Igor Fruman, another Florida-based businessman, were arrested last Wednesday at Dulles International Airport with one-way international tickets. They arrests came hours after they had lunch with Giuliani at the Trump International Hotel in Washington, D.C.

Federal authorities allege Parnas and Fruman violated campaign finance laws in order to funnel money to numerous Republican PACs and politicians, including a $325,000 contribution in May 2018 to the pro-Trump super PAC called America First Action.

Federal prosecutors in Manhattan are also reportedly investigating whether Giuliani’s dealing with Ukraine broke lobbying laws.
