" While most American unions supported the Marshall Plan as an economic boon for their members and a necessary defense measure for the West, Al Bernstein’s union did not. Along with all the other Communist-controlled unions in America, Al Bernstein’s United Public Workers attacked the Marshall Plan as a Cold War plot and launched an all-out campaign against it. On the political front, Al Bernstein and his comrades bolted the Democratic Party and organized the Progressive Party candidacy of Henry Wallace in the hope of unseating Truman and ending his anti-Communist program. Their actions were in fact a Soviet-orchestrated plot to sabotage the defense of Europe against Soviet aggression. "
