US intelligence obtains information that al-Qaeda is planning to infiltrate the US from Canada and carry out an operation using high explosives. The report does not say exactly where, when, or how an attack might occur. Two months later, the information is shared with the FBI, the INS, the US Customs Service, and the State Department, and it will be shared with President Bush in August. [US Congress, 9/18/2002; Washington Post, 9/19/2002] This information could come from captured al-Qaeda operative Ahmed Ressam, who warns around this month that al-Qaeda leader Abu Zubaida has been seeking Canadian passports as part of a plot to attack the US, possibly by planting explosives in several US cities (see May 30, 2001 and May 2001).

May 2001: CIA Official Connected to Cases of Moussaoui and Two 9/11 Hijackers Tasked to Help FBI
Tom Wilshire, a former deputy chief of Alec Station, the CIA’s bin Laden unit, is detailed to the FBI to help with its counterterrorism work. Wilshire was involved in the failure to watchlist 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar during the al-Qaeda Malaysia summit (see 9:30 a.m. – 4:00 p.m. January 5, 2000), and will also be involved in the failed search for them in the summer of 2001 (see May 15, 2001, Late May, 2001, and July 13, 2001), as well as the failure to obtain a search warrant for Zacarias Moussaoui’s belongings (see August 24, 2001). He acts as the CIA’s chief intelligence representative to Michael Rolince, head of the Bureau’s International Terrorism Operations Section. His primary role is apparently to help the FBI exploit information for intelligence purposes. [US Department of Justice, 11/2004, pp. 282-348

May 7, 2001: FBI Told of Plan to Attack Boston, New York, and London
A walk-in to an FBI office claims that there is a radical fundamentalist plot to launch attacks on Boston, New York, and London. The 9/11 Commission will later claim that the walk-in’s report was discredited, but it is unknown if this happened before or after 9/11. [9/11 Commission, 7/24/2004, pp. 255, 533] A declassified copy of the FBI warning obtained by the Intelwire website in 2008 will shed further light on the warning. Although parts of the warning are redacted, it appears the walk-in claims that three high-ranking al-Qaeda prisoners held in prison in Britain, Khalid al-Fawwaz, Adel Abdel Bary, and Ibrahim Eidarous, would launch the attack if they are extradited to the US. The warning claims that the attack has been planned for several years and operatives are already in the US to carry it out. The plan may involve a boat loaded with explosives or an attack on a large building. [Federal Bureau of Investigation, 5/7/2001 ] In August 2001, a different source will also claim to have learned of an attack on New York, possibly the World Trade Center, from the same three prisoners (see August 21, 2001).
May 11, 2001: New York City Practices for Biological Terrorist Attack
New York City’s Office of Emergency Management (OEM), which is located in World Trade Center Building 7, organizes a bio-terrorism drill where militant extremists attack the city with bubonic plague and Manhattan is quarantined. The “tabletop exercise” is called RED Ex—meaning “Recognition, Evaluation, and Decision-Making Exercise”
—and involves about seventy different entities, agencies, and locales from the New York area. Federal legislation adopted in 1997 requires federal, state, and local authorities to conduct regular exercises as part of the Domestic Preparedness Program (DPP). The US Defense Department chose New York City as the venue for RED Ex due to its size, prominence, and level of emergency preparedness. Various high-level officials take part, including Mayor Rudolph Giuliani, OEM Director Richard Sheirer, Fire Commissioner Thomas Von Essen, and Police Commissioner Bernard Kerik. Agencies and organizations that participate include New York City Fire Department, New York City Police Department, the FBI, and the Federal Emergency Management Agency (FEMA). The exercise is supposedly so intense that, according to one participant, “five minutes into that drill, everybody forgot it was a drill.”
[New York City Government, 5/11/2001; New York City Government, 9/5/2001, pp. 74 ; New York Sun, 12/20/2003; 9/11 Commission, 5/18/2004] According to OEM Director Richard Sheirer, “Operation RED Ex provided a proving ground and a great readiness training exercise for the many challenges the city routinely faces, such as weather events, heat emergencies, building collapses, fires, and public safety and health issues.”
[New York City Government, 5/11/2001] In his prepared testimony before the 9/11 Commission, Bernard Kerik later states: “The City, through its OEM, had coordinated plans for many types of emergencies; and those plans were tested frequently.” The types of emergencies they prepared for, he states, included “building collapses” and “plane crashes.”
[9/11 Commission, 5/18/2004 ] Considering Richard Sheirer’s comments, RED Ex appears to be one example where the city tests for building collapses. Details about training for airplanes crashing into New York City remain unknown. The second part of this exercise, called Tripod, is scheduled to take place in New York on September 12, 2001, but is cancelled due to the 9/11 attacks.
May 15, 2001: CIA Hides Al-Qaeda Malaysia Summit Information from the FBI
Tom Wilshire, a former deputy chief of the CIA’s bin Laden unit on attachment to the FBI, sends a request to CIA headquarters for the surveillance photos of the January 2000 al-Qaeda summit in Malaysia (see January 5-8, 2000). Three days later, Wilshire will explain the reason for his interest in an e-mail to a CIA analyst, writing, “I’m interested because Khalid Almihdhar’s two companions also were couriers of a sort, who traveled between [the Far East] and Los Angeles at the same time ([H]azmi and [S]alah).” Hazmi refers to future 9/11 hijacker Nawaf Alhazmi and Salah Said is the alias al-Qaeda leader Khallad bin Attash traveled under during the summit. Apparently, Wilshire will receive the photos. Toward the end of May, a CIA analyst will contact a specialist working at FBI headquarters about the photographs. The CIA wants the FBI analyst to review the photographs and determine if a person who had carried money to Southeast Asia for bin Attash in January 2000 could be identified. The CIA will fail to tell the FBI analyst anything about Almihdhar or Alhazmi. Around the same time, the CIA analyst will receive an e-mail mentioning Alhazmi’s travel to the US. These two analysts will travel to New York the next month and again the CIA analyst will fail to divulge what he knows. [US Congress, 7/24/2003 ; US Department of Justice, 11/2004, pp. 283 ]
May 15, 2001: CIA Officer Again Accesses Cables about Hijackers’ Travel in Asia and to US, Fails to Alert FBI or Check If They Are Still in US
Tom Wilshire, a former deputy chief of the CIA’s bin Laden unit currently detailed to the FBI, accesses a number of cables about travel by 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi in 2000 (see March 5, 2000), but fails to draw the FBI’s attention to this or ask the INS whether they are still in the US. The cables report on Khalid Almihdhar’s travel to Malaysia in January 2000, his US visa, al-Qaeda’s Malaysia summit, and Alhazmi’s travel from Kuala Lumpur, Malaysia, to Bangkok, Thailand, with another person, and then to Los Angeles. Wilshire had previously blocked a notification to the FBI that Almihdhar had a US visa (see 9:30 a.m. – 4:00 p.m. January 5, 2000). He writes to another CIA analyst about the travel (see May 15, 2001), but does not alert the FBI to the fact Alhazmi came to the US. Neither does he check with the INS to see whether Alhazmi and Almihdhar are in the country. When one of his colleagues finds these cables in late August, she will immediately check with the INS and become alarmed when she is told they are in the US (see August 21-22, 2001). [9/11 Commission, 7/24/2004, pp. 266-8, 537; US Department of Justice, 11/2004, pp. 283 ] The 9/11 Commission will explain his failure to alert the FBI by saying he was focused on a possible terrorist attack in Malaysia: “Despite the US links evident in this traffic, [Wilshire] made no effort to determine whether any of these individuals was in the United States. He did not raise the possibility with his FBI counterpart. He was focused on Malaysia.” [9/11 Commission, 7/24/2004, pp. 268]
Mid-May 2001: CIA Assigns Officer to Examine Malaysia Summit in Her Free Time
CIA manager Tom Wilshire recommends that an officer be assigned to review information about al-Qaeda’s Malaysia summit, to see if there are any connections between it and the attack against the USS Cole. The task is assigned to Margaret Gillespie, an agent on loan from the FBI. Author Lawrence Wright will comment: “[B]ut [Wilshire] did not reveal that some of the participants might be in the United States. More important, he conveyed none of the urgency reflected in [an e-mail he sent his superiors around this time]; he told [Gillespie] that she should examine the material in her free time. She didn’t get around to it until the end of July.” Perhaps partially due to the request’s lack of urgency, it seemingly takes Gillespie three months to work out what Wilshire already knows: that some of the 9/11 hijackers have entered the US. One reason is that a database search conducted by Gillespie is incomplete (see (Late May-Early June)). However, Gillespie will alert one of Wilshire’s associates at the FBI to the men’s presence in the US in late August (see August 21-22, 2001). [US Department of Justice, 11/2004, pp. 297-8 ; New Yorker, 7/10/2006 ]
Mid-May 2001: CIA Withholds Photo of Al-Qaeda Leader from FBI
Although three surveillance photographs of al-Qaeda’s Malaysia summit are passed to the FBI at this time (see Late May, 2001 and June 11, 2001), another key photograph the CIA has of the meeting is withheld by CIA officers Clark Shannon and Tom Wilshire. The key photograph shows al-Qaeda logistics manager Khallad bin Attash, who commanded the attack on the USS Cole (see October 12, 2000). Author Lawrence Wright will later comment: “Thanks to [FBI agent Ali] Soufan’s interrogation of [USS Cole bomber Fahad al-Quso], the Cole investigators had an active file on Khallad and were preparing to indict him. Knowledge of that fourth photo would likely have prompted [FBI manager John] O’Neill to demand that the CIA turn over all information relating to Khallad and his associates. By withholding the picture of Khallad attending the meeting with the future hijackers [Khalid Almihdhar and Nawaf Alhazmi], the CIA may in effect have allowed the September 11th plot to proceed.” [New Yorker, 7/10/2006 ] The CIA also has video and even more photos of the meeting (see January 5, 2000 and January 5-8, 2000 and Shortly After), but these are not shared either, and it is unclear how aware Wilshire and Shannon are of this additional material.
Late May-Early June: FBI Agent at CIA Searches Only One of Two Databases with Information about 9/11 Hijackers
Margaret Gillespie, an FBI agent detailed to the CIA who has been asked to research the connection between al-Qaeda’s Malaysia summit and the bombing of the USS Cole, checks a CIA database and finds some NSA information about 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi and their travel to an al-Qaeda summit in Kuala Lumpur, Malaysia, that was monitored by the US. The database she uses is Intelink, which only has information the CIA makes available to other intelligence agencies. However, she does not also examine the CIA’s Hercules database. It is unclear why she does not do so and whether, as an FBI agent, she has access to it. If she did access it, she would have a complete picture of the CIA’s knowledge of Almihdhar and Alhazmi and would know Almihdhar had a US visa and Alhazmi had traveled to the US (see January 2-5, 2000 and March 5, 2000). As Gillespie is only working this line of inquiry in her free time, she does not put together the information contained in the Hercules system until late August (see August 21-22, 2001). [Wright, 2006, pp. 340, 425]
Late May, 2001: CIA Officer Passes Three Malaysia Summit Photographs to FBI, but Fails to Mention Some Important Details
Tom Wilshire, a CIA officer on loan to the FBI, obtains three photographs from the surveillance of al-Qaeda’s Malaysia summit (see January 5-8, 2000), and passes them to Dina Corsi, an agent with the FBI’s bin Laden unit. Corsi learned of the photographs’ existence following a discussion with CIA officer Clark Shannon. Although Wilshire does not have a “substantive conversation” with Corsi about the photos, he does identify hijacker Khalid Almihdhar in one of them, and says Almihdhar traveled from Sana’a, Yemen, to Dubai, United Arab Emirates, and then Kuala Lumpur, Malaysia, in early January 2000. However, Wilshire omits to mention that Almihdhar has a US visa, his associate hijacker Nawaf Alhazmi has traveled to the US, or another associate, Khallad bin Attash, has been identified in the photos. He also does not say why the photos were taken. Author Lawrence Wright will later say the photos are passed because Wilshire wants to know what the FBI knows. The CIA says it thinks the photos may show Fahad al-Quso, an al-Qaeda operative involved in the USS Cole bombing. Corsi understands that the photos are “not formally passed” to the FBI, but are only for limited use at a forthcoming meeting. Therefore, only limited information about them is provided at the meeting, causing a disagreement (see June 11, 2001). However, Wilshire will later say that Corsi could give the photos to the FBI, but the FBI could not then give them to a foreign government (note: the photos had been provided to a foreign government five months previously, so this restriction is meaningless). [US Department of Justice, 11/2004, pp. 286-7, 293-4 ; New Yorker, 7/10/2006 ] Other pictures of the summit are available to the CIA, and there is even video footage (see February 2000 and Mid-May 2001), but these are not shared with the FBI or widely discussed.
