Oleg Deripaska: A Russian billionaire who is close to Russian president Vladimir Putin and has struggled to get visas to travel to the United States because of alleged ties to Russian organized crime, Oleg Deripaska employed Trump campaign chairman Paul Manafort as an investment consultant for years. At the time Manafort joined the Trump campaign in March 2016, Manafort owed Deripaska money and, through an aide, offered to give Deripaska “private briefings” about the campaign. Manafort and Deripaska have said the briefings never happened.
