September 4-5, 2001: 9/11 Hijacker Almihdhar’s Visa Is Revoked, but Inspectors Are Told Not to Detain Him

On August 31, 2001, 9/11 hijacker Khalid Almihdhar was placed in an INS and Customs lookout database, and described as “armed and dangerous” and someone who must be referred to secondary inspection (see August 31, 2001). On September 4, the State Department revokes Almihdhar’s visa for his “participation in terrorist activities.” On September 5, the INS entered the September 4 notice that Almihdhar’s visa has been revoked into the INS lookout system. However, it is also noted that the State Department has identified Almihdhar as a potential witness in an FBI investigation, and inspectors are told not to detain him. This information will appear in a little-noticed 9/11 Commission staff report released one month after the Commission’s Final Report. It will not be explained why the description of Almihdhar as armed and dangerous and to be referred to secondary inspection has been changed and who made the change. [9/11 Commission, 8/21/2004 ]
