From the article linked in my post:
People’s College of Law {Mayor Villaraigo's Alma Mata} was founded in 1974 “by people and organizations, including the Asian Law Collective, the La Raza National Lawyers Association (LRNLA), the National Conference of Black Lawyers (NCBL), and the National Lawyers Guild (NLG).And his long association with La Raza (NCLR) can been seen from the Google search result for the two: LINKThe NLG was for decades closely associated with the Communist Party.
Thanks—should have clicked the links first :)
