Phoenix, Arizona, FBI agent Ken Williams sends a memorandum warning about suspicious activities involving a group of Middle Eastern men taking flight training lessons in Arizona. The memo is titled: “Zakaria Mustapha Soubra; IT-OTHER (Islamic Army of the Caucasus),” because it focuses on Zakaria Soubra, a Lebanese flight student in Prescott, Arizona, and his connection with a terror group in Chechnya that has ties to al-Qaeda. It is subtitled: “Osama bin Laden and Al-Muhjiroun supporters attending civil aviation universities/colleges in Arizona.” [Fortune, 5/22/2002; Arizona Republic, 7/24/2003] Williams’ memo is based on an investigation of Sorba that Williams had begun in 2000 (see April 2000), but he had trouble pursuing because of the low priority the Arizona FBI office gave terror investigations (see April 2000-June 2001). Additionally, Williams had been alerted to suspicions about radical militants and aircraft at least three other times (see October 1996; 1998; November 1999-August 2001). In the memo, Williams does the following: 
Names nine other suspect students from Pakistan, India, Kenya, Algeria, the United Arab Emirates, and Saudi Arabia. [Die Zeit (Hamburg), 10/1/2002] Hijacker Hani Hanjour, attending flight school in Arizona in early 2001 and probably continuing into the summer of 2001 (see Summer 2001), is not one of the students, but, as explained below, it seems two of the students know him. [US Congress, 7/24/2003, pp. 135 
; Washington Post, 7/25/2003] Notes that he interviewed some of these students, and heard some of them make hostile comments about the US. Additionally, he noticed that they were suspiciously well informed about security measures at US airports. [Die Zeit (Hamburg), 10/1/2002] Notes an increasing, “inordinate number of individuals of investigative interest” taking flight lessons in Arizona. [Die Zeit (Hamburg), 10/1/2002; US Congress, 7/24/2003, pp. 135 ] Suspects that some of the ten people he has investigated are connected to al-Qaeda. [US Congress, 7/24/2003, pp. 135 ] One person on the list, Ghassan al Sharbi, will be arrested in Pakistan in March 2002 with al-Qaeda leader Abu Zubaida (see March 28, 2002). Al Sharbi attended a flight school in Prescott, Arizona. He also apparently attended the training camps in Afghanistan and swore loyalty to bin Laden in the summer of 2001. He apparently knows Hani Hanjour in Arizona (see October 1996-Late April 1999). He also is the roommate of Soubra, the main target of the memo. [Los Angeles Times, 1/24/2003; 9/11 Commission, 7/24/2004, pp. 521] Discovers that one of them was communicating through an intermediary with Abu Zubaida. This apparently is a reference to Hamed al Sulami, who had been telephoning a Saudi imam known to be Zubaida’s spiritual advisor. Al Sulami is an acquaintance of Hanjour in Arizona (see October 1996-Late April 1999). [Mercury News (San Jose), 5/23/2002; 9/11 Commission, 7/24/2004, pp. 520-521, 529] Discusses connections between several of the students and a radical group called Al-Muhajiroun. [Mercury News (San Jose), 5/23/2002] This group supported bin Laden, and issued a fatwa, or call to arms, that included airports on a list of acceptable terror targets. [Associated Press, 5/22/2002] Soubra, the main focus of the memo, is a member of Al-Muhajiroun and an outspoken radical. He met with Sheikh Omar Bakri Mohammed, the leader of Al-Muhajiroun in Britain, and started an Arizona chapter of the organization. After 9/11, some US officials will suspect that Soubra has ties to al-Qaeda and other terrorist groups. He will be held two years, then deported to Lebanon in 2004. [Los Angeles Times, 10/28/2001; Los Angeles Times, 1/24/2003; Arizona Republic, 5/2/2004; Arizona Monthly, 11/2004] Though Williams doesn’t include it in his memo, in the summer of 1998, Bakri publicized a fax sent by bin Laden to him that listed al-Qaeda’s four objectives in fighting the US. The first objective was “bring down their airliners.”
(see Summer 1998). [Los Angeles Times, 10/28/2001] Warns of a possible “effort by Osama bin Laden to send students to the US to attend civil aviation universities and colleges” [Fortune, 5/22/2002] , so they can later hijack aircraft. [Die Zeit (Hamburg), 10/1/2002] Recommends that the “FBI should accumulate a listing of civil aviation universities and colleges around the country. FBI field offices with these types of schools in their area should establish appropriate liaison. FBI [headquarters] should discuss this matter with other elements of the US intelligence community and task the community for any information that supports Phoenix’s suspicions.” [Arizona Republic, 7/24/2003] (The FBI has already done this, but because of poor FBI communications, Williams is not aware of the report.) Recommends that the FBI ask the State Department to provide visa data on flight school students from Middle Eastern countries, which will facilitate FBI tracking efforts. [New York Times, 5/4/2002]
The memo is addressed to the following FBI Agents: Dave Frasca, chief of the Radical Fundamentalist Unit (RFU) at FBI headquarters; Elizabeth Harvey Matson, Mark Connor and Fred Stremmel, Intelligence Operations Specialists in the RFU; Rod Middleton, acting chief of the Usama bin Laden Unit (UBLU); Jennifer Maitner, an Intelligence Operations Specialist in the UBLU; Jack Cloonan, an agent on the New York FBI’s bin Laden unit, the I-49 squad; (see January 1996 and Spring 2000). Michael S. Butsch, an agent on another New York FBI squad dealing with other Sunni terrorists. [Federal Bureau of Investigation, 7/10/2001 ; US Congress, 7/24/2003, pp. 135 ]
However, the memo is not uploaded into the FBI’s information system until the end of the month and is apparently not received by all these people (see July 27, 2001 and after). Williams also shares some concerns with the CIA (see (July 27, 2001)). [Mercury News (San Jose), 5/23/2002] One anonymous government official who has seen the memo says, “This was as actionable a memo as could have been written by anyone.” [Insight, 5/27/2002] However, the memo is merely marked “routine,” rather than “urgent.” It is generally ignored, not shared with other FBI offices, and the recommendations are not taken. One colleague in New York replies at the time that the memo is “speculative and not very significant.” [Die Zeit (Hamburg), 10/1/2002; US Congress, 7/24/2003, pp. 135 ] Williams is unaware of many FBI investigations and leads that could have given weight to his memo. Authorities later claim that Williams was only pursuing a hunch, but one familiar with classified information says, “This was not a vague hunch. He was doing a case on these guys.” [Mercury News (San Jose), 5/23/2002]
July 27, 2001 and after: Phoenix Memo Received by FBI Headquarters; Little Action Taken in Response
FBI headquarters receives the Phoenix Memo, but does not act on it. The memo was drafted by Arizona FBI agent Ken Williams and warns that a large number of Islamic extremists are learning to fly in the US. It is dated 17 days earlier, but is not uploaded until this date (see July 10, 2001). Although the memo is addressed to eight specific agents, it is apparently not received by all of them. The Justice Department’s Office of Inspector General will later say that the memo was not delivered directly to the addressees, but uploaded to a central dispatching point, from where it was assigned to Radical Fundamentalist Unit agent Elizabeth Matson on July 30. Before sending the memo, Williams called both Matson and her colleague Fred Stremmel to talk to them about it. Matson pulls up the memo, which has “routine” precedence, and prints and reads it. However, she thinks it should go to the bin Laden unit. A week later she discusses the matter with bin Laden unit agent Jennifer Maitner and they agree that Maitner will do some research and then they will talk again. Matson will later tell the Office of Inspector General she may have mentioned the memo to her superior, but is not sure. Her superior will say he was not consulted. Maitner discusses the memo with bin Laden unit chief Rod Middleton and also sends it to the FBI’s Portland, Oregon, field office, which was previously interested in one of the men named in the memo. However, she does not do anything else with it before 9/11, apparently due to her high workload. The FBI will later acknowledge the memo did not receive the sufficient or timely analysis that it deserved. [US Department of Justice, 11/2004, pp. 65-77, 80 ] The memo is also seen by the FBI’s New York field office (see July 27, 2001 or Shortly After), another RFU agent researching the Moussaoui case (see August 22, 2001) and possibly the CIA’s bin Laden unit (see (July 27, 2001)).
August 23, 2001: FBI Manager Informed of Hunt for 9/11 Hijacker Almihdhar, Realizes Seriousness of Situation
Dina Corsi, an FBI agent in the bureau’s bin Laden unit, informs her boss, bin Laden unit supervisor Rodney Middleton, that 9/11 hijacker Khalid Almihdhar is in the US. [US Department of Justice, 11/2004, pp. 303 ] Middleton will later recall his reaction to the news as an “‘Oh sh_t’ moment.” [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 52 ] He reviews the information Corsi presents to him and agrees with her that an intelligence investigation should be opened in New York to find Almihdhar. [US Department of Justice, 11/2004, pp. 303 ]
Shortly After August 23, 2001: Top FBI Official Possibly Notified of Search for 9/11 Hijacker Almihdhar
After 9/11, no clear evidence that any of the FBI’s top managers are informed of the search for hijacker Khalid Almihdhar will be uncovered and the 9/11 Commission will comment, “It appears that no one informed higher levels of management in either the FBI or CIA about the case.” However, the Commission will also note that “one witness recalls a discussion with a senior FBI official, that official denies that a discussion took place. The other alleged participant does not recall such a meeting.” The list of sources that follows this passage indicates that the senior official is International Terrorism Operations Section chief Michael Rolince, who is also informed of the Moussaoui case around this time, but will attempt to play down his knowledge of it (see Late August 2001 and March 21, 2006), and the other participants are two of the following: FBI headquarters agent Dina Corsi, CIA officer Tom Wilshire, and acting head of the FBI’s bin Laden unit Rod Middleton. [9/11 Commission, 7/24/2004, pp. 270, 538]
August 28, 2001:ColeAgent Argues with FBI Headquarters over Search for 9/11 Hijacker Almihdhar
FBI New York agent Steve Bongardt, FBI headquarters agent Dina Corsi, and acting FBI Osama bin Laden unit head Rod Middleton, who is Corsi’s supervisor, discuss whether the search for future 9/11 hijacker Khalid Almihdhar should be an intelligence or criminal investigation. Bongardt argues that the search should be a criminal investigation because of Almihdhar’s connection to the bombing of the USS Cole and because more agents could be assigned to a criminal investigation. (Note: the office only has one rookie intelligence agent available.) He also says a criminal investigation would have better tools, such as grand jury subpoenas, which are faster and easier to obtain than the tools in an intelligence investigation. Corsi and Middleton say that the “wall” prevents the intelligence information necessary for the case being shared with criminal investigators, so the search must be an intelligence investigation. (Note: Corsi and Middleton are wrong (see August 29, 2001).) Bongardt is unhappy with this and requests an opinion from the Justice Department’s national security law unit (see August 28-29, 2001). [US Department of Justice, 11/2004, pp. 307 ]
August 28-29, 2001: FBI Headquarters Allegedly Misrepresents Attorney’s Advice, Ensuring Search for 9/11 Hijacker Almihdhar Is Intelligence Investigation
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).
August 30, 2001: CIA Finally Tells FBI Al-Qaeda Leader Met 9/11 Hijackers in Malaysia, but Information Is Withheld from Investigators
The CIA finally tells the FBI that al-Qaeda leader Khallad bin Attash attended an al-Qaeda summit in Malaysia in January 2000 with future 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi (see January 5-8, 2000). The CIA monitored the meeting and has known that bin Attash attended it for at least eight months (see January 4, 2001), but repeatedly failed to tell the FBI of this (see Shortly Before February 1, 2001, February 1, 2001, Mid-May 2001, and June 11, 2001). The CIA will later say that it thought the FBI knew of the identification in January 2001 (see January 5, 2001 and After), but a CIA manager asked for permission to pass the information to the FBI in July 2001, implying he knew the FBI did not have the information (see July 13, 2001). [US Department of Justice, 11/2004, pp. 298, 305, 310 ] In addition, the text of the notifiction states, “We wish to advise you that, during a previously scheduled meeting with our joint source,” bin Attash was identified in a surveillance photo. [US Congress, 7/24/2003, pp. 150 ] The cable containing the information is for Rodney Middleton, acting head of the FBI’s bin Laden unit, and also says that, if the FBI thinks it does not have all the photographs it needs of the Malaysia summit, it should ask the CIA for them. Middleton is aware that the FBI is investigating Almihdhar (see August 29, 2001), but there is no record of him or anyone else providing this information to either the agent investigating Almihdhar or the main investigation of the USS Cole bombing, which bin Attash commanded. The information was requested by FBI agent Dina Corsi and was passed through a CIA Counterterrorist Center representative to the FBI, presumably Tom Wilshire. Although one of bin Attash’s aliases was watchlisted one week ago (see August 23, 2001), he is not watchlisted under his real name even at this point, meaning the commander of the USS Cole attack can enter the US under his own name as he pleases. [US Department of Justice, 11/2004, pp. 298, 305, 310 ]
2:30 p.m. September 11, 2001: New York FBI Agent Recognizes the Name of a Hijacker during a Conference Call with FBI Headquarters
A number of FBI agents in New York are told the names of some suspected hijackers during a conference call with FBI headquarters in Washington, DC, and one of the agents, Steve Bongardt, is enraged when he recognizes one of these men, Khalid Almihdhar, as someone the FBI has been investigating. Most agents from the FBI’s New York office have assembled at a temporary field office at 26th Street and the West Side Highway (see After 10:28 a.m. September 11, 2001). But members of the FBI’s I-49 squad, which is focused on Osama bin Laden and al-Qaeda’s central command, have returned to their office at 290 Broadway. Three of them now participate in a conference call with FBI headquarters. Along with Bongardt, Kenneth Maxwell, the agent in charge of counterterrorism in New York, and John Liguori, a supervisor at the New York office, are on the call. Those at headquarters who are on it include Michael Rolince, head of the FBI’s international terrorism operations section, supervisor Rod Middleton, and analyst Dina Corsi. Maxwell begins the discussion, asking: “What do we know? Do we recognize any of the hijacker names?” Corsi says they have some names of suspected hijackers and starts reading these out. When she mentions Almihdhar, Bongardt interrupts her, asking: “Khalid Almihdhar? The same one you told us about? He’s on the list?” [Graff, 2011, pp. 313; Soufan, 2011, pp. 290-291] “This is the same Almihdhar we’ve been talking about for three months!” he yells angrily. [Washington Post, 9/21/2002] “Steve, we did everything by the book,” Middleton explains. “I hope that makes you feel better; tens of thousands are dead!” Bongardt retorts. Maxwell then tries to calm his colleague down. He presses the mute button on the phone and tells Bongardt: “Now is not the time for this. There will be a time, but not now.” [Graff, 2011, pp. 313; Soufan, 2011, pp. 290-291] Sometime tonight, Bongardt will submit a request to the FBI information center. “Within hours,” he will later recall, the center gets back to him after finding Almihdhar’s address in San Diego, California, simply through searching “public resources.” [US Congress. Senate. Committee on Intelligence, 9/20/2002]
