Jacob Golos was the "main pillar" of the [[NKVD]] intelligence network. He had worked with Soviet intelligence from the mid 1930s, and probably earlier. He was not merely a CPUSA official assisting the NKVD (an agent or “probationer” in Soviet intelligence parlance) but held official rank in the NKVD, and claimed to be a an oldtime ''[[Chekist]]''. Golos headed the Central Control Commission (discipline) which planned the execution of [[Juliet Poyntz]], an American defector from the [[GRU]]. <ref>Anthony Cave Brown and Charles B.
