Sen.. Jeff Klein over the last several days has picked up endorsements from a key environmental organization and labor union in his re-election bid.

Klein on Wednesday was endorsed by the New York League of Conservation Voters, which praised his 92 percent voting record with the group’s preferred legislation.

“It is an honor to receive NYLCV’s endorsement. Now more than ever, New York State must fight destructive federal policies, and lead the nation when it comes to advancing progressive environmental legislation,” Klein said.

“I have stood side by side with NYLCV in the fight to improve conditions in our public housing, transform food deserts, promote smart transportation solutions, protect our waterfronts, and build resilient infrastructure. I am proud and truly grateful to receive NYLCV’s support.”

Klein on Thursday was among the lawmakers given the backing of the Building and Construction Trades Council, a politically active construction labor union.

“This distinguished slate of candidates will fight for policies that benefit working families and solidify a pathway to the middle class,” said Gary LaBarbera, president of the 100,000 member Building and Construction Trades Council of Greater New York. “The BCTC Executive Board is proud to endorse these candidates and we look forward to working together to ensure good paying jobs with benefits and an economy that works for everyone.”

Klein is the former leader of the Independent Democratic Conference, a faction of Democrats that folded in April and rejoined the mainline conference under an agreement reached with Gov. Andrew Cuomo.

Klein next month faces Alessandra Biaggi in a Democratic primary on Sept. 13.

Earlier this year, Klein was accused by a former staffer of forcibly kissing her in a 2015 incident. Klein has denied the allegation and has sought an investigation by the Joint Commission on Public Ethics.
