A former member organization of the Blue Green Alliance (BGA) was the Laborers’ International Union of North America (LIUNA). LIUNA left BGA in January 2012, in response to attacks on the Keystone XL pipeline by some of the Alliance’sother member groups. LIUNA General President Terry O’Sullivan said, “We’re repulsed by some of our supposed brothers and sisters lining up [against Keystone] with job killers like the Sierra Club and the Natural Resources Defense Council to destroy the lives of working men and women.”
