Amid Scrutiny, Paul Manafort Leaves Republican Convention Role

Paul Manafort, the longtime Republican strategist and chairman of Donald J. Trump’s 2016 campaign, who had assumed an unpaid role advising party officials on the nominating convention, stepped aside on Saturday after questions arose about his involvement in the convention’s planning process.

Mr. Manafort’s move came after The New York Times reported that he had been on the ground in Milwaukee last week for planning meetings for the convention, as well as a Washington Post story that said he was involved in work connected to foreign officials and businesses.
