John Podesta and Robby Mook

Veteran D.C. power broker and now campaign chair, Podesta, left, was Bill Clinton’s chief of staff and is seen as the grown-up in the room who can speak to Bill and Hillary as an equal. Campaign manager Mook, right, 36, ran Nevada and Ohio for Hillary Clinton in 2008, and is known for a fiercely loyal following among campaign staff and his cheapskate ways.
