In news from the campaign trail, longtime Republican political operative Paul Manafort has quit his position as chair of Donald Trump’s campaign. Manafort’s resignation came on Friday. Trump had appointed Stephen Bannon, the executive chair of the right-wing media outlet Breitbart News, to be his campaign’s chief executive earlier in the week. Manafort is facing questions about his years of political consulting work in Ukraine, where he advised former President Viktor Yanukovych. The New York Times has reported that handwritten ledgers unearthed in Ukraine show $12.7 million of cash payments that were slated to go to Manafort—although it is not known whether he ever received the money.
