Another possible Roth fallback: He could have had Questadt, "who belongs to Roth," subpoena Fredo or whomever was the Corleone successor to testify before the Senate subcommittee (the hearings were scheduled and would have been held with or without Michael). Fredo or whomever would have to plead the Fifth, which would destroy any "legitimacy" and invite the Gaming Commission to revoke their licenses.
