“Jim Cooper is one of the brightest Members of Congress. He understands the issues and offers sound solutions,” said Rep. Jim Turner (Texas), one of the leaders of the Blue Dogs. “Jim brings a depth of experience and knowledge to the Blue Dog Coalition that will enhance our efforts to return Washington to a path of fiscal responsibility and balanced budgets.”

While Cooper is serving his first term as the Representative for Tennessee’s 5th district, he previously served six terms in the state’s 4th district. He sits on the Armed Services, Budget and Government Reform committees.

Treasury Hire. John Emiling is leaving his post as chief of staff in House Chief Deputy Majority Whip Eric Cantor’s (R-Va.) personal office to join the Treasury Department’s legislative affairs shop, where he will serve as deputy assistant secretary for tax and budget issues.

Before joining Cantor’s office, Emiling put in stints with the National Federation of Independent Business, the Senate Republican Policy Committee and ex-Reps. Bob Livingston (R-La.) and Bob Walker (R-Pa.).

Cantor’s new top aide in his personal office will be Rob Collins, who will add chief of staff duties to his current portfolio as communications director.
