Perlo group

Headed by Victor Perlo, the Perlo group is the name given to a group of Americans who provided information which was given to Soviet intelligence agencies; it was active during the World War II period, until the entire group was exposed to the FBI by the defection of Elizabeth Bentley.[1]

It had sources on the War Production Board, the Senate La Follette Subcommittee on Civil Liberties, and in the United States Department of Treasury.[citation needed]
