Senate Minority Leader Len Fasano will not seek re-election this fall, his office confirmed Tuesday night.

Senate President Pro Tempore Martin M. Looney said he was saddened by the news.

“Len is a pillar of the General Assembly and leaves a distinguished legacy as a true statesman of the Connecticut Senate,” Looney said. “While we may serve as leaders of different parties, Len and I have worked together countless times to solve problems, help people in need, and get vital things done. In particular, over the past several years we have coauthored significant health care consumer protection legislation that stands as a model for other states. The Senate circle will not be the same without him.”

Fasano, a lawyer who was first elected in 2002, was unavilable for comment Tuesday. His district includes Durham, East Haven, North Haven and Wallingford. He has led the Republican caucus since 2014. It was in the minority except for the years 2017 and 2018, when there was a tie in the Senate and Republicans had co-chairmen on the various committees.

The vacancy could attract wide interest, including Rep. Craig Fishbein, R-Wallingford, Rep. Joe Zullo, R-East Haven, and Democratic former East Haven Mayor April Capone.

In the General Assembly, Len Fasano has served as leader of the Senate Republican Caucus since 2014.
