 Though Wallace was not a member of the PCA, he was widely regarded as the organization's leader and was criticized for the PCA's acceptance of Communist members.In response to the creation of the PCA, anti-Communist liberals established a rival group, Americans for Democratic Action (ADA), which explicitly rejected any association with Communism.Wallace strongly criticized the president in early 1947 after Truman promulgated the Truman Doctrine and issued Executive Order 9835, which began a purge of government workers affiliated with political groups deemed to be subversive.
