A classified report by the FBI’s Investigative Services Division says: “In addition to frequent and sustained interaction between and among the hijackers of the various flights before September 11, the group maintained a web of contacts both in the United States and abroad. These associates, ranging in degrees of closeness, include friends and associates from universities and flight schools, former roommates, people they knew through mosques and religious activities, and employment contacts. Other contacts provided legal, logistical, or financial assistance, facilitated US entry and flight school enrollment, or were known from [Osama bin Laden]-related activities or training.” [Sperry, 2005, pp. 67-68] But in June 2002, FBI Director Robert Mueller will contradict this, saying: “To this day we have found no one in the United States except the actual hijackers who knew of the plot.… As far as we know, they contacted no known terrorist sympathizers in the United States” (see June 18, 2002).
