"Trump’s top adviser, Paul Manafort, has spent much of his recent career working for pro-Russian forces in Ukraine, and doing complex deals for an oligarch with close ties to Putin. And while a Democratic senator has already charged Trump is not responsible enough to receive secret information, Manafort’s deep relationships with top pro-Russian figures raise special concerns. Manafort may be best known for managing the 2010 campaign of Viktor Yanukovych, the Ukrainian politician whose ouster as president prompted a Russian invasion of the country. He has, according to court documents, managed tens of millions of dollars for Oleg Deripaska, an oligarch denied entry to the U.S. reportedly for ties to organized crime, but so close to Vladimir Putin that top Russian officials fought (unsuccessfully) to get him a visa."
