Donald Trump’s campaign chairman Paul Manafort resigned Friday morning, the candidate announced in a statement. “This morning Paul Manafort offered, and I accepted, his resignation from the campaign,” Trump said. “Paul is a true professional and I wish him the greatest success.” Despite the kind words, Trump essentially demoted Manafort this week by hiring Brietbart News executive Steve Bannon and pollster Kellyanne Conway to run the campaign. With Manafort’s resignation, Trump is moving on to his third campaign manager this year. Former manager Corey Lewandowski was fired in June, after Trump’s first polling collapse just after he clinched the Republican nomination. Manafort was helping Trump marshal delegates for the convention when he was promoted. Manafort, a longtime D.C. insider and lobbyist, has come under scrutiny for his ties to Russia during his work in Ukraine for the country’s former president.
