Rep. Steve Israel (N.Y.) promoted an internal candidate to be the new executive director of the Democratic Congressional Campaign Committee.

Israel, the new DCCC chairman, announced Monday that Robby Mook would be the committee's next top staffer.

Mook led the DCCC's Independent Expenditure effort in the 2010 cycle, during which the party lost more than 60 seats and its majority. He replaces outgoing Executive Director Jon Vogel.

"Robby has the right combination of experience, political know-how and leadership savvy to help make this the shortest Republican majority in history," Israel said in a statement.
