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 4-5, 2001: Phoenix Memo Agent Vets Bush PDB, Fails to Add Relevant Information, Does Not Contact Phoenix Office
The CIA officers who draft a presidential daily briefing (PDB) item given to George Bush on August 6 (see August 6, 2001) ask an FBI agent for additional information and also to review a draft of the memo, but she does not provide all the additional information she could. The 9/11 Commission will refer to the FBI agent as “Jen M,” so she is presumably Jennifer Maitner, an agent with the Osama bin Laden unit at FBI headquarters. The purpose of the memo is to communicate to the president the intelligence community’s view that the threat of attacks by bin Laden is both current and serious. But Maitner fails to add some important information that she has: around the end of July, she was informed of the Phoenix memo, which suggests that an inordinate number of bin Laden-related Arabs are taking flying lessons in the US (see July 10, 2001). She does not link this to the portion of the memo discussing aircraft hijackings. Responsibility for dealing with the Phoenix memo is formally transferred to her on August 7, when she reads the full text. The finished PDB item discusses the possibility bin Laden operatives may hijack an airliner and says that there are “patterns of suspicious activity in this country consistent with preparations for hijackings.” It is unclear whether the draft PDB item Maitner reviews contains this information. However, if it does, it apparently does not inspire her to take any significant action on the memo before 9/11, such as contacting the agents in Phoenix to notify them of the preparations for hijackings (see July 27, 2001 and after). The PDB will contain an error, saying that the FBI was conducting 70 full field investigations of bin Laden-related individuals (see August 6, 2001), but this error is added after Maitner reviews the draft, so she does not have the opportunity to remove it.
