 Truman responded to Wallace's left-wing challenge by pressing for liberal domestic policies, while pro-ADA liberals like Hubert Humphrey, Robert F. Wagner, and James Roosevelt linked Wallace to the Soviet Union and the Communist Party.Many Americans came to see Wallace as a fellow traveller to Communists, a view that was reinforced by Wallace's refusal to condemn the 1948 Czechoslovak coup d'état.In early 1948, the CIO and the AFL both rejected Wallace, with the AFL denouncing him as a "front, spokesman, and apologist for the Communist Party".
