 Firtash's attorneys obtained a September 2019 statement from Viktor Shokin, the former Ukrainian prosecutor general who was forced out under pressure from multiple countries and non-governmental organizations, as conveyed to Ukraine by then-vice president Joe Biden.Shokin asserted in the statement that Biden actually had him fired because he refused to stop his investigation into Burisma, a Ukrainian energy firm that employed Biden's son.President Donald Trump's personal attorney, Rudy Giuliani, who asserts he has "nothing to do with Firtash," has promoted the statement in television appearances as purported evidence of wrongdoing by the Bidens.
