FBI headquarters agents Dina Corsi and Rod Middleton contact Justice Department lawyer Sherry Sabol to ask her opinion on the search for 9/11 hijacker Khalid Almihdhar, but Sabol will later say that Corsi misrepresents her advice to other agents. Corsi contacts Sabol, an attorney at the national security law unit, to ask her about legal restrictions on the search for Almihdhar, because of an argument she has had with New York agent Steve Bongardt about whether the search should be an intelligence or criminal investigation (see August 28, 2001 and August 28, 2001). Corsi will later tell Bongardt that Sabol told her that the information needed for the investigation cannot be passed on to criminal agents at the FBI, only intelligence agents, and that if Almihdhar is located, a criminal agent cannot be present at an interview. [US Department of Justice, 11/2004, pp. 307-8 ] Corsi’s understanding of the issue is wrong, and the “wall,” which restricted the passage of some intelligence information to criminal agents at the FBI, does not prevent the information in question being shared with criminal agents (see August 29, 2001). The 9/11 Commission will comment that Corsi “appears to have misunderstood the complex rules that could apply to the situation.” [9/11 Commission, 7/24/2004, pp. 271] In addition, Sabol will later insist that her advice was very different than what Corsi claims it is. She will deny saying a criminal agent could not interview Almihdhar, arguing that she would not have given such inaccurate advice. She will also say the caveat on the intelligence information from the NSA would not have stopped criminal agents getting involved and, in any case, the NSA would have waived the caveat if asked. (Note: the NSA did so at Corsi’s request just one day earlier (see August 27-28, 2001), but presumably Corsi does not tell Sabol this.) [9/11 Commission, 7/24/2004, pp. 271] Larry Parkinson, the FBI’s general counsel at this time, will later say there was no legal bar to a criminal agent being present at an interview and that he would be shocked if Sabol had actually told Corsi this. [9/11 Commission, 2/24/2004] Furthermore, Corsi apparently does not tell Sabol that Almihdhar is in the US illegally. The illegal entry is a crime and means criminal FBI agents can search for him (see August 29, 2001).
