Wallace was also hurt when Westbrook Pegler, a prominent conservative newspaper columnist, revealed that Wallace as vice president had written coded letters discussing prominent politicians such as Franklin Roosevelt and Winston Churchill to his controversial Russian New Age spiritual guru Nicholas Roerich; the letters were nicknamed the "Guru letters." In his book "Out of the Jaws of Victory", the journalist Jules Abels wrote: "Personalities were referred to by symbolic titles—Roosevelt was 'The Flaming One', Churchill 'The Roaring Lion', and Cordell Hull 'The Sour One'... some of the letters were signed 'Wallace', others 'Galahad'", the name that Roerich had assigned Wallace in his cult. This revelation—including direct quotes from the letters—led to much ridicule of Wallace in the national press. The Progressive Party Convention, which was also held in Philadelphia, was a highly contentious affair; several famous newspaper journalists, such as H. L. Mencken and Dorothy Thompson, publicly accused the Progressives of being covertly controlled by Communists. The party's platform was drafted by Lee Pressman, the convention secretary; he later admitted that he had been a member of the Communist party. John Abt served as legal counsel to the convention's permanent chairman, Albert Fitzgerald; he also testified years later that he was a Communist. Rexford Tugwell, a prominent liberal in President Franklin Roosevelt's New Deal, served as the Chairman of the party's platform committee. He became convinced that the party was being manipulated by Communists, and was "so heartsick about Communist infiltration of the party that he discussed . . . with his wife disaffiliating the party the night before the convention" started. Tugwell later did disassociate himself from the Progressive Party and did not participate in Wallace's fall campaign. A number of other Progressive Party delegates and supporters would quit the party in protest over what they perceived as the undue influence Communists exerted over Wallace, including the prominent American socialist Norman Thomas. In the fall, Thomas would run as the Socialist Party presidential candidate to offer liberals a non-Communist alternative to Wallace.
