In any prosecution for an offense, it is an affirmative defense that the accused was granted immunity from prosecution for that offense by the Attorney General or a Deputy Attorney General or by court order pursuant to § 3506 of this title. It is also an affirmative defense that the accused was granted immunity from prosecution for a different offense when prosecution for the offense now charged would have been barred by prosecution for the offense as to which immunity was granted under § 208 of this title; provided, that the Attorney General or a Deputy Attorney General may, in granting immunity, stipulate that the immunity applies only to a specific offense, in which case effect shall be given to the stipulation.
