Associates of a Ukrainian oligarch fighting extradition to the U.S. were working to dig up dirt on former Vice President Joe Biden last summer in an effort to get Rudy Giuliani's help in the oligarch's legal case, according to three people familiar with the exchanges.
Dmitry Firtash, charged with conspiracy by the U.S. and living in Vienna, shuffled lawyers in July to add Joe diGenova and Victoria Toensing, vocal supporters of President Donald Trump who had worked with Giuliani. Around that time, some of Firtash's associates began to use his broad network of Ukraine contacts to get damaging information on Biden, the people said.
- diGenova and Toensing are frequent legal commentators on Fox News and were at one point supposed to join the Trump legal team during the Mueller investigation but it eventually fell through; Toensing lobbied Trump extensively and ultimately successfully on Fox News for a pardon of her client Scooter Libby
- Firtash is an Ukrainian oligarch with extensive, extensive ties to Russia's elite and Russian intelligence and worked alongside Manafort a decade ago in Ukraine to help elect the pro-Russian president Yanukovych (who had to flee to Russia in 2014 after the Maidan protests)
- Lev Parnas, one of the four indicted Giuliani associates, worked as a translator for Firtash; Parnas and Fruman were heading to Austria, where Firtash lives, before they got arrested last week; Giuliani said previously he had flown to Austria before but not to visit Firtash (which is probably a lie)
TIME's reporting provides more context about Firtash:
tl;dr: Corrupt Ukrainian oligarch is awaiting extradition to the US, paid Giuliani associates $1M to dig up dirt on Biden in hopes Giuliani would get Trump to drop the extradition request (or: quid pro quo)
