illustrates why the continued influence of oligarchs will likely hamper the country’s drive to reform. In October 2014, George Soros named Naftogaz to be "a black hole in the budget and a major source of corruption" and called for a radical reform of the company, which could "totally eliminate Ukraine's dependence on Russia for gas". Radio Free Europe/Radio Liberty produced a short documentary entitled "The Palaces of Ukraine's Oil and Gas Men" about the homes of Naftogaz management during the presidency of Viktor Yanukovych, who was overthrown in 2014. In October 2019, Naftogaz got caught up in the impeachment proceedings against President Donald Trump in the US, when news broke that a group of businessmen with allegedly close ties to the President and his personal lawyer, Rudy Giuliani, intervened in an attempt to change the management of Naftogaz. An Associated Press report reveals how businessmen Lev Parnas, Igor Fruman and Harry Sargeant III allegedly attempted to replace Naftogaz CEO, Andriy Kobolyev, and sought to broker a deal to sell their own natural gas to the company.
