Brooklyn Sen. Marty Golden received a boost this morning with an endorsement from 1199 SEIU.

The endorsement comes as Golden has received the backing of several private-sector unions, but was dumped by the state AFL-CIO, whose rank-and-file decided to support his Democratic challenger Andrew Gounardes.

“I am proud to have 1199 SEIU’s endorsement. Their mission is to improve and expand quality patient care and to protect and improve the lives of those suffering from illnesses and infirmities. I have fought tirelessly for legislation to promote and aid the membership of 1199 SEIU in providing a higher level of health care support for all New Yorkers, and will continue to work to make our communities a better place to live, work, and raise a family,” Golden said in a statement.

The labor group said in a statement that it planned to conduct phone banking and GOTV operations for Golden this election season.
