The German American Bund, or the German American Federation, was a German-American Nazi organization which was established in 1936 as a successor to the Friends of New Germany. The organization chose its new name in order to emphasize its American credentials after the press accused it of being unpatriotic. The Bund was allowed to consist only of American citizens of German descent. Its main goal was to promote a favorable view of Nazi Germany.

Samuel Dickstein was a Democratic Congressional Representative from New York, a New York State Supreme Court Justice, and a Soviet spy. He played a key role in establishing the committee that would become the House Committee on Un-American Activities, which he used to attack fascists, including Nazi sympathizers, and suspected communists. In 1999, authors Allen Weinstein and Alexander Vassiliev learned that Soviet files indicate that Dickstein was a paid agent of the NKVD.
