Sunrise Boston, a group that is focused on “climate change through political action,” has endorsed Brandy Fluker-Oakley, one of four Democrats running for the 12th Suffolk seat in the Massachusetts House that is being vacated by state Rep. Dan Cullinane.

It also gave its nod to incumbent US Rep. Ayanna Pressley in a round of endorsements announced on Monday.

“Housing, transportation, and climate issues are intrinsically linked,” said Scott Gilman, electoral lead of Sunrise Boston. “Brandy’s support of increasing transit accessibility and rent stabilization policies demonstrates both a deep understanding of the needs of her district and a strong alignment with Sunrise’s priorities.”

Fluker-Oakley, a Mattapan attorney, will appear on the Sept. 1 primary ballot alongside Stephanie Everett, Jovan Lacet, and Cameron Charbonnier.
