Alger Hiss, Harry Dexter White? Well.. even without Stalin asking, his people were trying to help him settle the score with Imperial Japan -- others including O. John Rogge were helping Stalin; to wit, FDR pressured DOJ to prosecute his (FDR's) critics. The critics were mostly anti-Stalin, anti-communists who had opposed the war prior to Pearl Harbor. DoJ assigned O. John Rogge to be the prosecutor.
Rogge had been a good friend of Soviet dictator Josef Stalin, was involved in numerous communist front groups, and had visited Russia, where he spoke in the Kremlin and laid a wreath at the grave of American Communist Party co-founder John Reed in Red Square. His wreath was inscribed: “In loving memory from grateful Americans.” . . . Rogge was an American delegate to a world communist “peace conference” in Paris and was a lawyer for many communists in trouble with the law. He was the attorney for David Greenglass, the atomic spy who saved his own life by turning state’s evidence against his sister and brother-in-law, Ethel and Julius Rosenberg [who] went to the electric chair for turning over U.S. atomic secrets to the Soviets. [Rogge] was thus eventually exposed for what he was. No wonder he was so fanatical in his hatred against the Sedition Trial defendants, all of whom were anti-communists.
I like to mention A Mockery of Justice The Great Sedition Trial of 1944 often.. because I see Great "Sedition" Trials of 201x - 201x" a coming.
As with these kind of events, it's much more to it than the average person will ever know.
