Donald Trump's campaign chairman Paul Manafort faced questions on Sunday morning about his alleged ties to Russia and whether the campaign is any way working with Russian President Vladimir Putin. "No," Manafort said on ABC. "It's absurd. There's no basis for it." Manafort has worked for Ukrainian clients in the past and the recent release of DNC emails, possibly from Russian hackers, led some to suggest that the campaign was colluding with the Russian president.
