When Rudy Giuliani crony Lev Parnas was arrested last month, federal agents combed through his personal effects and found the business card of a Ukrainian prosecutor who, months earlier, met with Giuliani to discuss the conspiracy theories at the heart of the Trump impeachment inquiry.

Anti-corruption prosecutor Nazar Kholodnytsky’s card was among the 66 personal items that the FBI reported seizing from Parnas after his arrest at Washington’s Dulles International Airport last month, according to an itemized list of the effects obtained by PAY DIRT. It’s not clear when or how Parnas obtained that card, but his arrest came months after Giuliani met Kholodnytsky in Paris for a discussion that touched on Joe Biden and his son Hunter, and supposed Ukrainian interference in the 2016 presidential election.

Kholodnytsky was caught on tape earlier this year apparently suborning false testimony and tipping off prosecution targets to impending raids. He claims the recordings were taken out of context. But Marie Yovanovitch, until this year the U.S. ambassador to Ukraine, called for Kholodnytsky’s removal. Instead, Yovanovitch was recalled after a sustained lobbying campaign by Giuliani, Parnas, and his political and business associate Igor Fruman.
