The government prosecuted one Department of Defense employee (Franklin) and two lobbyists (Rosen & Weissman) for the American Israel Public Affairs Committee (AIPAC) for allegedly disclosing national defense information to persons "not entitled" to have it, a crime under the Espionage Act of 1917 (18 U.S.C. § 793).
The cases against Rosen and Weissman were also unusual because this aspect of the Espionage act had rarely (if ever) been used against non-government individuals.
The government flipped Franklin some time before 2003; he became convinced by the FBI that Rosen and Weissman were doing bad things.
[2][3] The indictment contains a timeline of events it alleges to have occurred; a description of the conspiracy that it claims happened.
It also lists occasions where Rosen and Weissman allegedly gave false statements to the FBI about Franklin.
