" The Ukrainian people would soon find out how ironclad these assurances were. The corrupt Viktor Yanukovych had returned to power in the last election, thanks to the efforts of the equally crooked political consultant Paul Manafort, whose office manager in Kyiv, Konstantin Kilimnik, had deep ties to Russian intelligence. Their paymasters included tycoons enmeshed with both organized crime and the Kremlin. Manafort collected many millions in fees from Yanukovych, laundering them in offshore accounts, and attracting the attention of the FBI, which began wiretapping him in a foreign intelligence investigation. Manafort also cut business deals with the country’s richest and most odious oligarchs, including Dmytro Firtash, a Putin crony and a prominent associate of Russian organized crime indicted on federal corruption charges in Chicago in October 2013.
