The indictment revealed that the investigation had been going on since 1999, and suggested that other individuals at AIPAC, the Defense Department and the Israeli embassy had been involved as well. The indictment also alleged that Kenneth Pollack, a National Security Council staffer during the Clinton administration (and director of research at the Brookings Institution's Saban Center for Middle East Policy) provided information to former AIPAC employees Steve J. Rosen and Keith Weissman. This allegation was not part of any of the legal proceeding in this case.
