From LA Weekly:
The Weekly has learned that Chicago-based special agent Robert Wright has accused the agency of shutting down his 1998 criminal probe into alleged terrorist-training camps in Chicago and Kansas City. The apparent goal of the training camps, according to confidential documents obtained by the Weekly, was to recruit and train Palestinian-American youths, who would then slip into Israel. Recruits at these camps reportedly received weapons training and instruction in bomb-making techniques in the early 1990s. The bomb-making curriculum included the sort of explosives later used in the 1995 Oklahoma City bombing. And government documents state that two trainees came from the Oklahoma City area.
