Hoover and the Communist Party

Vinoana itself ended up sort of infiltrated by famous spies like Kim Filby and so who was a British intelligence officer who was also a Soviet agent. because they want to keep this program super secret they find people who are involved even in atomic espionage and they can't do anything about it. Hoover kind of played him right but on the one hand he convinced McCarthy that he was his guy and then on the other hand he totally undermined it.
