Marion Bachrach was the sister of John Abt and also a member of the Ware group, a group of government employees in the New Deal administration of President Franklin Roosevelt who were also members of the secret appartus of the Communist Party of the United States (CPUSA) in the 1930s. Bachrach was the personal secretary and congressional office manager to Representative John Bernard of the Minnesota Farmer-Labor Party in 1937-1938. Bachrach also was a correspondent for the newspaper PM.
Membership and meeting of the Ware group were highly secretive, and many members eventually infiltrated into higher levels of the United States government during World War II. After Alger Hiss was cut out from closer contact with the Ware group, Hiss remained a close associate of Marion Bachrach.
On November 20, 1942 Soviet foreign intelligence (Dimitrov to Fitin, RTsKhIDNI 495-74-484) requested a background report on Bachrach from the Comintern and received a positive report.
Marion Bachrach wrote several tracts sold to Communist consumers. Some original publications appear to be quite profitable among collectors and sellers. Among them are Amnesty! Proposal of an amnesty program to release the members of the Communist Party imprisoned under the provisions of the Smith Act, This Obvious Violence, You Are on Trial and The Federal Grand Jury is Stacked Against You.
