U.S. Rep. Rosa DeLauro, a 15-term Democrat from New Haven and the dean of the Connecticut delegation, has been selected as the chairman of the powerful House Appropriations Committee. DeLauro, a close ally of House Speaker Nancy Pelosi, replaces retiring U.S. Rep. Nita Lowey of New York. She won the gavel by a vote of 148 to 79 over U.S. Rep. Debbie Wasserman Schultz. A third contender for the post, U.S. Rep. Marcy Kaptur of Ohio, dropped her bid early Thursday and endorsed DeLauro. he House Appropriations Committee has one of the broadest jurisdictions of any congressional committee, overseeing nearly every aspect of government spending. Having a member of the state’s delegation leading such a key committee could be a boon for Connecticut. The state has never had a member of its delegation chair the committee.
