A lawsuit seeking disclosure of FBI files that may detail a U.S.-based support network for the 9/11 hijackers has reached a federal appeals court, which is being asked by a Florida online publication to order a Freedom of Information Act trial on the dispute.

The case centers around reporting published by floridabulldog.org on the FBI’s investigation into a Saudi family that abruptly left its home in a gated Sarasota community two weeks before the 2001 terror attacks. One FBI document written in 2002 that was disclosed in court said agents had found “many connections” between the family and some of the hijackers who took flying lessons at a nearby airport, including ringleader Mohamed Atta.
