Sen. Joseph Lieberman (I-Conn.), who has worked to help credit unions achieve several of their legislative goals, announced today that he won't run for a fifth term next year.
Lieberman, an independent who has caucused with Democrats, has faced increasing political challenges at home because of his willingness to work with Republicans on a range of issues. He was first elected in 1988 after defeating Sen. Lowell Weicker (R-Conn.)
Lieberman was the Senate sponsor of the Credit Union Regulatory Improvements Act, which included risk-based capital reform and raises the member business lending cap.
Lieberman left the Democratic Party after losing the party's primary in 2006 and then won a three-way general election race as an independent. CUNA's political action committee gave his campaign $6,000.
He is the third senator to announce he won't seek another term next year.
