Late July 2001 (B): David Schippers, noted conservative Chicago lawyer and the House Judiciary Committee's chief investigator in the Clinton impeachment trial, later claims that FBI agents in Chicago and Minnesota contact him around this time and tell him that a terrorist attack is going to occur in lower Manhattan. According to Schippers, the agents had been developing extensive information on the planned attack for many months. However, the FBI soon pulls them off the terrorist investigation and threatens them with prosecution under the National Security Act if they go public with the information. As a result, they contact Schippers hoping he can persuade the government to take action. Schippers tries to pass the information on to high government officials but apparently his efforts are ignored. Partly in conjunction with Judicial Watch, the public interest law firm, Schippers is now representing at least ten FBI agents in a suit against the US government in an attempt to have their testimony subpoenaed, which would enable them to legally tell what they know without going to jail. [Judicial Watch, 11/14/01, Alex Jones Show, 10/10/01, World Net Daily, 10/21/01, note the sources are partisan, Schipper's claims are being reported nowhere else]
