A founding member of the Communist Party of the United States of America (CPUSA), circa 1930 Golos became involved in the covert work of Soviet intelligence agencies. He participated in procuring American passports by means of fraudulent documentation, and the recruitment and coordination of activities of a broad network of agents.
