In 1948, Anatoly Gorsky, former chief of Soviet intelligence operations in the United States, listed Pressman, code-named "Vig," among the Soviet sources likely to have been identified by US authorities, as a result of the defection of Soviet courier Elizabeth Bentley three years earlier [REF].
A 1951 Soviet intelligence report indicated that "Vig" had "chosen to betray us," apparently a reference to his 1950 public statements and Congressional testimony [REF].
