Trump's campaign manager Kellyanne Conway and Clinton aide Robby Mook clashed Thursday as they offered their behind-the-scenes perspectives on the 2016 presidential contest at a forum.

The email, from Clinton's campaign manager Robby Mook, said Obama administration officials should use their connections in the president's home state to try to push back the March 15 Illinois primary by at least a month.

Hillary Clinton's campaign manager did a round on the weekly talk shows where he raised the suggestion that Russian actors are looking to undermine her in an attempt to elect Donald Trump.
