Margaret Gillespie, an FBI agent detailed to the CIA who has just found out that future 9/11 hijacker Khalid Almihdhar is in the US (see August 21-22, 2001), suggests asking failed Millennium bomber Ahmed Ressam whether he recognizes Almihdhar, but the proposal is not acted on. Ressam was arrested on his way to bomb Los Angeles airport (see December 14, 1999), but has been co-operating with the US government against al-Qaeda (see May 30, 2001). Gillespie makes the suggestion in an e-mail to Tom Wilshire, a CIA representative to the FBI. It is unclear what Wilshire does with the suggestion, but Ressam is not interviewed. When shown photos of Almihdhar after 9/11, Ressam will not recognize him. The FBI also fails to ask Ressam about Zacarias Moussaoui before 9/11, but shortly after 9/11 Ressam will identity Moussaoui as a person that attended al-Qaeda’s camps in Afghanistan (see Late August-Early September 2001).

Before August 22, 2001: FBI Headquarters Agent Learns Al-Qaeda Leader Attended Malaysia Summit with 9/11 Hijackers, Investigation Fails to Discover How
FBI headquarters agent Dina Corsi learns that al-Qaeda leader Khallad bin Attash attended a summit in Malaysia that was also attended by 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi (see January 5-8, 2000); an e-mail sent by Corsi on this date contains the first reference in FBI documents to bin Attash’s presence at the Malaysia summit. Although it is her job to support the investigation into the attack on the USS Cole (see October 12, 2000), which bin Attash commanded, and she is aware that bin Attash is important to the Cole investigation, even saying that she is focused on his identity and whereabouts, she fails to communicate this information to the agents investigating the bombing, who do not receive it before 9/11 (see August 30, 2001). After 9/11, she will say she cannot recall how she learned this information and an investigation by the Justice Department’s Office of Inspector General will fail to find any documents that cast light on the matter. Although she does not do anything with this information before another FBI agent tells her Khalid Almihdhar is in the US (see August 21-22, 2001), she will later say that the information bin Attash was at the Malaysia summit was important, as it connected Almihdhar and Alhazmi to the Cole bombing. She will also say that CIA officers Tom Wilshire and Clark Shannon, who she discussed al-Qaeda’s Malaysia summit with and who knew that bin Attash was in Malaysia with Alhazmi and Almihdhar (see Late May, 2001, Mid-May 2001 and June 11, 2001), did not give her this information. Although Corsi and others know that bin Attash is an important al-Qaeda leader, he is not watchlisted at this point, although one of his aliases is watchlisted in August (see August 23, 2001).

August 22, 2001: Top FBI Al-Qaeda Expert Leaves FBI in Frustration; Misses Important Warnings on Moussaoui and Two 9/11 Hijackers
Counterterrorism expert John O’Neill retires from the FBI. He says it is partly because of the recent power play against him, but also because of repeated obstruction of his investigations into al-Qaeda. [New Yorker, 1/14/2002] In his last act, he signs papers ordering FBI investigators back to Yemen to resume the USS Cole investigation, now that Barbara Bodine is leaving as ambassador (they arrive a couple days before 9/11). He never hears the CIA warning about hijackers Nawaf Alhazmi and Khalid Almihdhar sent out just one day later. He also apparently is not told about the arrest of Zacarias Moussaoui on August 15, 2001 [PBS, 10/3/2002] ; nor does he attend a June meeting when the CIA reveals some of what it knows about Alhazmi and Almihdhar. [PBS Frontline, 10/3/2002] ABC News reporter Chris Isham will later say, “John had heard the alarm bells, too, and we used to talk about it. And he knew that there was a lot of noise out there and that there were a lot of warnings, a lot of red flags, and that it was at a similar level that they were hearing before the millennium, which was an indication that there was something going on. And yet he felt that he was frozen out, that he was not in a capacity to really do anything about it anymore because of his relationship with the FBI. So it was a source of real anguish for him.” [PBS, 10/3/2002]
August 22, 2001: CIA Officer Who Already Knows of Almihdhar and Alhazmi’s US Travel Is Informed of it by FBI, Agrees Investigation Should Start
After FBI agents Margaret Gillespie and Dina Corsi learn that 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi may be in the US (see August 21-22, 2001), they call a meeting with Tom Wilshire, a CIA officer interested in the investigation who is on loan to the FBI. Although all three will later be unable to recall the specifics of the conversation, they agree that it is important to initiate an investigation to locate Almihdhar. However, Wilshire has been aware that Almihdhar has a US visa since January 2000, when he frustrated the passage of such information to the FBI (see 9:30 a.m. – 4:00 p.m. January 5, 2000). He is also already aware that Alhazmi entered the US in January 2000 (see May 15, 2001) but again does not share this with the FBI. [US Department of Justice, 11/2004, pp. 301-2 ]
August 22, 2001: FBI Team Returns to Yemen to InvestigateColeBombing
An FBI team returns to Yemen to re-commence its investigation of the bombing of the USS Cole (see October 12, 2000). The team, headed by FBI agent Ali Soufan and sent by retiring FBI manager John O’Neill on his last day with the FBI (see August 22, 2001), had been pulled out of Yemen in June, due to possible threats against it (see June 17, 2001). On the same day as Soufan leaves, the CIA finally tells the FBI some of what it knows about 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi, and their attendance at an al-Qaeda’s Malaysia summit (see August 21-22, 2001 and August 23, 2001). Soufan had requested information about the Malaysia summit from the CIA three times (see Late November 2000, April 2001 and July 2001), but the CIA had repeatedly failed to respond to his requests. While in Yemen, Soufan appears not to be aware of the new information provided to the FBI, and learns about the Malaysia summit shortly after the 9/11 attacks (see January 5-8, 2000 and September 12-Late September, 2001). [New Yorker, 7/10/2006 ]
August 22-September 10, 2001: Unclear If Bin Laden Unit Briefs Top CIA Management about 9/11 Hijacker Almihdhar’s Presence in US; Unit Chief Knows He Is Likely Attacker
It is unclear if Alec Station, the CIA’s bin Laden unit, briefs CIA leaders on information that 9/11 hijacker Khalid Almihdhar is in the US. Margaret Gillespie, an FBI analyst detailed to the station, discovers that Almihdhar is in the US on August 21, immediately informs the FBI (see August 21-22, 2001), and places Almihdhar, hijacker Nawaf Alhazmi, and two more associates on the TIPOFF watch list the next day (see August 23, 2001). The CIA also forwards information about al-Qaeda leader Khallad bin Attash to the FBI on August 30 (see August 30, 2001).
No Information on Briefings – There is no indication that Richard Blee, the CIA manager responsible for Alec Station, or anyone at Alec Station informs the CIA’s leadership, the White House, or Richard Clarke’s Counterterrorism Security Group (see August 23, 2001) of Almihdhar’s presence in the US and the clear implications of this presence. For example, no such briefing will be mentioned in the 9/11 Commission Report, although the report will mention that CIA Director George Tenet is briefed about Zacarias Moussaoui around the same time, and it does discuss the circulation of the information about Almihdhar at the FBI in detail. [9/11 Commission, 7/24/2004, pp. 268-277] The 9/11 Congressional Inquiry will not mention any such briefing, although it will discuss how the FBI handles the information. [US Congress, 7/24/2003, pp. 151-4 ] No such briefing will be mentioned in a 2007 book by Tenet, although the book will mention a briefing Tenet receives about Moussaoui. [Tenet, 2007, pp. 158-160, 200] The Justice Department inspector general’s report will discuss the FBI’s handling of the information in detail. [US Department of Justice, 11/2004, pp. 297-313 ] However, the full CIA inspector general’s report about 9/11 will not be made public, and its executive summary will not mention any such briefing. [Central Intelligence Agency, 6/2005, pp. 15-16 ]
Alec Station Aware of Threat and Almihdhar – Alec Station, the CIA, and the US intelligence community in general are highly aware that preparations for a large al-Qaeda attack are in the final stages (see Shortly After July 5, 2001, June 28, 2001, and June 28, 2001). Blee is, in fact, the lead briefer within the government about the threats, and has briefed not only his superiors at the CIA, but also National Security Adviser Condoleezza Rice (see May 30, 2001 and June 28, 2001). He has also recently expressed the belief that the attack will be in the US (see Late July 2001) and has apparently received a series of e-mails in which his former deputy told him Almihdhar may well be involved in the forthcoming attack (see July 5, 2001, July 13, 2001, and July 23, 2001). The information that Almihdhar is in the US therefore confirms Blee’s belief that the attack will be in the US, but it appears Alec Station fails to pass this information on.
August 23, 2001: FBI Field Agent Tells FBI Headquarters Search for 9/11 Hijacker Almihdhar Should Be Criminal, Not Intelligence Investigation
After being alerted to the fact 9/11 hijacker Khalid Almihdhar is in the US, FBI agent Craig Donnachie says that the FBI should look for him under a criminal investigation, not an intelligence investigation. Donnachie, an intelligence agent at the FBI’s New York field office, is contacted by headquarters agent Dina Corsi, who says that the search for Almihdhar should be an intelligence investigation because the case is partially based on information from the NSA. Donnachie, however, tells her that the attempt to locate Almihdhar is related to the criminal investigation into the bombing of the USS Cole and would normally be handled as a sub-file of the main investigation, not a separate investigation. The case will later be opened as an intelligence investigation, meaning fewer resources can be devoted to it (see August 29, 2001). [US Department of Justice, 11/2004, pp. 304 ]
August 23, 2001: 9/11 Hijackers Alhazmi and Almihdhar Are Finally Added to Terrorist Watch List
Thanks to the request of Margaret Gillespie, an FBI analyst assigned to the CIA’s Counter Terrorism Center, the CIA sends a cable to the State Department, INS, Customs Service, and FBI requesting that “bin Laden-related individuals” Nawaf Alhazmi, Khalid Almihdhar, Ahmad Hikmat Shakir, and Salah Saeed Mohammed bin Yousaf (an alias for Khallad bin Attash) be put on the terrorism watch list. All four individuals had attended the January 2000 al-Qaeda summit in Malaysia (see January 5-8, 2000). The cable mostly focuses on Almihdhar, briefly outlining his attendance at the Malaysia summit and his subsequent travel to the US in January 2000 and July 2001. Since March 2000, if not earlier, the CIA has had good reason to believe Alhazmi and Almihdhar were al-Qaeda operatives living in the US, but apparently did nothing and told no other agency about it until now. The hijackers are not located in time, and both die in the 9/11 attacks. FBI agents later state that if they been told about Alhazmi and Almihdhar sooner, “There’s no question we could have tied all 19 hijackers together” given the frequent contact between these two and the other hijackers. [Newsweek, 6/2/2002; 9/11 Commission, 7/24/2004, pp. 538; US Department of Justice, 11/2004, pp. 32-36, 302] However, in what the Washington Post calls a “critical omission,” the FAA, the Treasury Department’s Financial Crimes Enforcement Network, and the FBI’s Financial Review Group are not notified. The two latter organizations have the power to tap into private credit card and bank data, and claim they could have readily found Alhazmi and Almihdhar, given the frequency the two used credit cards. [Washington Post, 7/25/2003] Furthermore, counterterrorism chief Richard Clarke and his Counterterrorism Security Group are not told about these two operatives before 9/11 either. [Newsweek, 3/24/2004] The CIA later claims the request was labeled “immediate,” the second most urgent category (the highest is reserved for things like declarations of war). [Los Angeles Times, 10/28/2001] The FBI denies that it was marked “immediate” and other agencies treated the request as a routine matter. [Los Angeles Times, 10/18/2001; US Congress, 9/20/2002] The State Department places all four men on the watch list the next day. [US Congress, 7/24/2003 ] However, this watch list, named TIPOFF, checks their names only if they use international flights. There is another watch list barring suspected terrorists from flying domestically. On 9/11, it contains only 12 names, including Khalid Shaikh Mohammed and other al-Qaeda figures, and some names are added as late as August 28, 2001. But none of these four men are added to this domestic list before 9/11.(see April 24, 2000). [9/11 Commission, 1/26/2004]
August 23, 2001: FBI Agent Discusses Opening of Intelligence Investigation with CIA Officer, Notes 9/11 Hijacker Almihdhar Has Stronger Link to USSColeBombing
FBI headquarters agent Dina Corsi writes to Tom Wilshire, a CIA manager detailed to the FBI, and tells him that the search for 9/11 hijacker Khalid Almihdhar will be conducted as an intelligence investigation (see August 23, 2001 and August 29, 2001). She also says that she is surer now that Almihdhar is connected to the bombing of the USS Cole, writing, “I am still looking at intel, but I think we have more of a definitive connection to the Cole here than we thought.” Even though Corsi thinks Almihdhar is tied to the Cole bombing, she will oppose the search for him being conducted as part of the criminal investigation and insist that it be part of an intelligence investigation (see August 28, 2001 and August 28, 2001). [US Department of Justice, 11/2004, pp. 304 ]
August 23, 2001: FBI Headquarters Gives New York Field Office Heads Up Over 9/11 Hijacker Almihdhar, but Investigation Is Not Considered Urgent
FBI headquarters agent Dina Corsi, who has discovered 9/11 hijacker Khalid Almihdhar is in the country (see August 21-22, 2001), contacts the FBI’s New York field office to give it a heads up that information about Almihdhar will soon be passed to it, and it will be asked to search for him. Corsi does not usually call in advance of sending notification, but she thinks that the situation is urgent in this case, as they need to locate Almihdhar, who is watchlisted at this time (see August 23, 2001), before he leaves the US. However, when she sends written notification (see August 28, 2001), it only has “routine” precedence, the lowest level. When asked about the discrepancy after 9/11, Corsi will say that this case was “no bigger” than any other case. I-49 squad supervisor Jack Cloonan and another FBI supervisor will later also say they recognized there was some urgency to the Almihdhar investigation, but the Justice Department’s Office of Inspector General will comment: “Yet, the FBI in New York did not treat it like an urgent matter.” [US Department of Justice, 11/2004, pp. 303-5, 354 ]
