In 1952, Fast ran for Congress on the American Labor Party ticket. During the 1950s he also worked for the Communist newspaper, the "Daily Worker". In 1953, he was awarded the Stalin Peace Prize. Later that decade, Fast broke with the Party over issues of conditions in the Soviet Union and Eastern Europe, particularly after Nikita Khrushchev's report "On the Personality Cult and its Consequences" at a closed session of the 20th Congress of the Communist Party of the Soviet Union in February 1956, denouncing the personality cult and dictatorship of Joseph Stalin, and the Soviet military intervention to suppress the Hungarian Revolution of 1956 in November. In his autobiographical work titled "The Naked God: The Writer and the Communist Party" published in 1957, he wrote: "There was the evil in what we dreamed of as Communists: we took the noblest dreams and hopes of mankind as our credo; the evil we did was to accept the degradation of our own souls—and because we surrendered in ourselves, in our own party existence, all the best and most precious gains and liberties of mankind—because we did this, we betrayed mankind, and the Communist party became a thing of destruction."
