Trump national political director 'steps back' from campaign

Donald Trump's national political director, Jim Murphy, said Thursday he is stepping back from the Republican nominee's campaign.

"I have not resigned but for personal reasons have had to take a step back from the campaign," Murphy said, as first reported by Politico.

Murphy was brought on to the campaign in June and is a close friend of Trump's former campaign chairman Paul Manafort.

He previously managed floor operations at three GOP conventions, and was an adviser to Bob Dole's 1988 and 1996 presidential campaigns.
