WASHINGTON (AP) — Republican Rep. C.W. Bill Young, Florida’s longest-serving member of Congress and a lawmaker who has been influential on military spending during his 43 years in Washington, has decided to retire.

Young said he will serve the rest of his term, which ends next year. His district is expected to be up for grabs, and Wednesday’s announcement makes it likely that Democrats will pour additional resources into the district during the 2014 election.
