Washington (CNN) Lev Parnas, the indicted associate of Rudy Giuliani, has told associates that he and his business partner, Igor Fruman, discussed Ukraine with President Donald Trump at an April 2018 donor dinner, The Washington Post reported Tuesday.

Parnas told associates that he and Fruman informed Trump that then-US Ambassador to Ukraine Marie Yovanovitch was unfavorable to the President and his interests, according to the Post. Trump responded by immediately stating Yovanovitch should be fired, people familiar told the paper.

A former senior administration official told the Post that Giuliani repeatedly updated Trump about Parnas' and Fruman's efforts in Ukraine.

Reports of the President discussing Ukraine with Parnas and Fruman at a dinner more than a year ago undercut Trump's repeated claim that he doesn't know the pair.

Parnas and Fruman were detained at Dulles International Airport in October. The men -- both central to the impeachment inquiry in the House -- were arrested and indicted on criminal charges of funneling foreign money to US elections. They pleaded not guilty in a Manhattan federal court last month.
