Absolutely! Thanks for that link. A couple highlights:
Firtash is an “upper-echelon” associate of Russian organized crime, according to a 2017 Justice Department court filing. He told a U.S. ambassador of his consultations with the notorious Russian mob boss Semion Mogilevich, according to a leaked U.S. diplomatic cable…
As the founder of RosUkrEnergo, Firtash acted as a middleman between the Russian and Ukrainian national natural gas companies, and allegedly played a central role in a corrupt scheme to use the profits from reselling cheap Russian gas to fund pro-Russia political forces in Ukraine.
Firtash worked with Paul Manafort on an abortive effort in 2008 to redevelop a New York hotel for $895 million. Firtash also reportedly played a role in Manafort’s 2005 hiring as a consultant to the Party of Regions, the pro-Russian political party of which Firtash was a major backer.
John Herbst, who served as ambassador to Ukraine under George W. Bush, said the association with Firtash undermines the entire effort by Trump allies to push for investigations of the Bidens and alleged Ukrainian election interference. "The Giuliani team does not understand Ukraine. If it did, members of his team would not be representing Dmytro Firtash, perhaps the most odious oligarch in Ukraine,” said Herbst, now director of the Eurasia Center at the Atlantic Council. “Shokin’s defense of Firtash underscores that he was never and is not today a fighter against corruption.”
“It’s preposterous,” said Adrian Karatnycky, a Ukraine expert and former president of the pro-democracy NGO Freedom House, of the story laid out in the affidavit. Pointing to Firtash’s Kremlin ties, he said, "There is now a distinct possibility of a Russian hand in all this.”
…
And Firtash isn’t the only Ukrainian oligarch with big legal problems who now faces questions from investigators: On Monday, the House Oversight Committee demanded documents and communications related to influential billionaire Ihor Kolomoisky as part of its subpoena of Giuliani.The involvement of Kolomoisky and Firtash complicates the already mind-boggling array of factions and agendas that form the backdrop of the Ukraine scandal. Because both face potential criminal liability in the U.S., both have reason to align themselves with Trump and try to ingratiate themselves to the president’s allies, according to Ukraine experts.
But the exact nature of Kolomoisky’s role in this saga isn’t yet clear. …
The rest of the article gives some fascinating background on Kolomoisky and his possible connections to this scandal, but at this point he’s still in the “watch this space” category.
