Towards the end of an interview with the FBI (see August 16-17, 2001), Zacarias Moussaoui discloses the name of one of his associates, Atif Ahmed. Moussaoui tells the FBI that Ahmed provided him with some money and that he associated with Ahmed’s brother in Pakistan. However, he cannot remember any details, such as Ahmed’s address or employment. The FBI’s Minneapolis field office immediately sends a lead to its legal attaché in London, asking him to follow up. However, information about Ahmed does not arrive in the US until “months later,” possibly November 2001, when Ahmed is arrested in Britain (see Mid-November 2001). [US District Court for the Eastern District of Virginia, Alexandria Division, 3/9/2006] Moussaoui will later say that Ahmed is a spy working for the British, but the FBI and British authorities will deny this (see July 25, 2002).
August 17-November 11, 2001 and After: FBI Fails to Check Moussaoui Computer Lead
When Zacarias Moussaoui is arrested (see August 16, 2001), he has a receipt on him for a Kinko’s store where he used a computer on August 12. The FBI does not go to this Kinko’s store to collect information about Moussaoui immediately after the arrest, but only on September 19, after the rest of Moussaoui’s belongings have been searched (see September 11, 2001). The FBI is told that the computers have been wiped and no information about Moussaoui’s use can be obtained. Due to the frequency with which Kinko’s computers are wiped, if the FBI visited the Kinko’s store immediately after the arrest, it is possible information about Moussaoui could have been recovered. Although the FBI is initially aware of some of Moussaoui’s e-mail addresses, in summer 2002 Moussaoui will reveal additional addresses he used and say he used them from this Kinko’s outlet. Although the Kinko’s computers have been wiped by 9/11, Microsoft, which operates the Hotmail service Moussaoui uses, can recover information up to 90 days after an account is last used, so the FBI could get the information it seeks from Microsoft until Mid-November 2001 (see (Late July-Early August, 2002)). However, the FBI does not know about the additional accounts at this point, partly because it was prevented from interviewing Moussaoui after 9/11 (see September 11-12, 2001). [US District Court for the Eastern District of Virginia, Alexandria Division, 1/1/2003]
August 18, 2001 or Shortly Before: Minneapolis FBI Contacts CIA Headquarters for Help with Moussaoui Case
Minneapolis FBI agent Harry Samit contacts Charles Frahm, an FBI agent who is working with the CIA’s bin Laden unit as a deputy chief, to discuss the Moussaoui case. Frahm passes on information to other CIA officers. Frahm will also be contacted by FBI headquarters about the case (see (August 20, 2001)) and will provide information linking the Chechen rebels, to which Moussaoui is connected, to Osama bin Laden and al-Qaeda (see August 24, 2001). [Tenet, 2007, pp. 201]
August 19, 2001: New York Times Reports that the FBI Is Investigating Its Top Al-Qaeda Expert
An article in the New York Times reveals that the FBI has launched an internal investigation of John O’Neill, one of its most senior counterterrorism officials, for losing a briefcase that contained highly classified information. [New York Times, 8/19/2001] O’Neill, special agent in charge of the FBI’s national security division in New York, had his briefcase, which contained his division’s annual field office report, stolen when he left it unattended during a conference in Orlando, Florida, in July 2000 (see July 2000). The briefcase was found a few hours later with the report still in it. [Wright, 2006, pp. 317; Graff, 2011, pp. 260] However, the FBI’s Office of Professional Responsibility immediately launched an investigation to determine whether any criminal charges should be brought against O’Neill. [Weiss, 2003, pp. 281] That investigation recently ended with a decision not to prosecute, but the FBI’s internal affairs unit subsequently began an investigation to determine whether O’Neill had violated FBI rules. According to the Times: “FBI officials were alarmed, in part, because of the sensitivity of the documents involved, including details about the bureau’s counterterrorism and counterintelligence operations. One document contained highly sensitive information about an FBI source.” [New York Times, 8/19/2001]
Story Appears Timed to Stop O’Neill Getting a Job on the NSC – The New Yorker will later comment that the leaking of the details of the FBI investigation to the Times “seemed to be timed to destroy O’Neill’s chance of being confirmed for [a National Security Council] job.” The leak was “somebody being pretty vicious to John,” Thomas Pickard, acting FBI director, will say. [New Yorker, 1/14/2002]
Several Officials Will Be Suspected of Being the Article’s Source – A number of people will be suspected of leaking the details of the investigation to the Times. [Weiss, 2003, pp. 347] O’Neill will suspect Pickard. The acting director “was out to get John for a long time and John never really knew why,” Valerie James, O’Neill’s longtime girlfriend, will say. Pickard will deny being the leaker, though, when O’Neill confronts him about the issue. [PBS, 10/3/2002] Other possible sources of the leak, according to journalist and author Murray Weiss, include Dale Watson, assistant director of the FBI’s counterterrorism division; Barbara Bodine, the US ambassador to Yemen; and Richard Clarke, the White House counterterrorism chief. [Weiss, 2003, pp. 347]
O’Neill Has Overseen Major Terrorism Investigations – O’Neill’s job is among the most powerful in the FBI, and O’Neill has overseen cases such as the bombings of the US embassies in Kenya and Tanzania in August 1998 (see 10:35-10:39 a.m., August 7, 1998), and the attack on the USS Cole in Yemen in October 2000 (see October 12, 2000). [New York Times, 8/19/2001] He is the FBI’s “most committed tracker of Osama bin Laden and his al-Qaeda network of terrorists,” according to the New Yorker. But he will retire from the FBI on August 22 and take up a new job as head of security at the World Trade Center a day later (see August 22, 2001 and August 23, 2001). [New Yorker, 1/14/2002; Weiss, 2003, pp. 349-350]
Before August 22, 2001: Threat Information about ‘Khalid’ Increases Interest in 9/11 Hijacker Almihdhar
The CIA receives some threat information about a man named “Khalid” and begins to examine data on everybody it knows whose first name is “Khalid”. In an August 22 e-mail FBI agent Dina Corsi writes that this is one of the reasons for the interest in hijacker Khalid Almihdhar at this time: “the reason [the intelligence community] were looking at [Almihdhar] is relatively general—basically they were looking at all individuals using the name Khalid because of some threat information.” [US Department of Justice, 11/2004, pp. 285 
] The identity of the man named Khalid they are looking for is not revealed, however, there is threat reporting starting in June 2001 concerning someone an informant called Khalid, who is later revealed to be Khalid Shaikh Mohammed (see June 12, 2001).
August 20, 2001: 9/11 Hijacker Atta Announces Approximate Date of Attack in E-mail to Bin Al-Shibh in Germany
In an interview with Al Jazeera journalist Yosri Fouda in 2002 (see April, June, or August 2002), would-be hijacker Ramzi bin al-Shibh will claim that, roughly around this day, he receives a coded chat room message about the 9/11 plot from future hijacker Mohamed Atta in the US. Fouda will later co-write a book, and in it he will allege that bin al-Shibh gave him a computer disc containing the exact message. The message, as translated by Fouda, reads: 
“The first semester commences in three weeks. There are no changes. All is well. There are good signs and encouraging ideas. Two high schools and two universities. Everything is going according to plan. This summer will surely be hot. I want to talk to you about some details. Nineteen certificates for private education and four exams. Regards to the Professor. Goodbye.”
Fouda will claim that the message is in code, and that bin al-Shibh discussed with him what the real meaning was. In his book, Fouda says the real meaning is this: “The zero hour is going to be in three weeks’ time. There are no changes. All is well. The brothers have been seeing encouraging visions and dreams. The Twin Towers, the Pentagon, and Capitol Hill. Everything is going according to plan. This summer will surely be hot. I want to talk to you about some details. Nineteen hijackers and four targets. Regards to Khalid Shaikh Mohammed or Osama bin Laden [Fouda isn’t sure which one is the ‘Professor’]. I will call you nearer the time.”
Bin al-Shibh also tells Fouda that “This summer will surely be hot” is a reference to the damage the attacks will cause. [Guardian, 9/9/2002; Fouda and Fielding, 2003, pp. 138-139, 146]
When Were the Exact Date and Targets Chosen? – Future hijacker Hani Hanjour makes surveillance test flights near the Pentagon and World Trade Center around this time, suggesting the targets for the 9/11 attacks have now been confirmed (see July 20, 2001 and Mid-August 2001). [CBS News, 10/9/2002] The FBI will later notice spikes in cell phone use between the hijackers just after the arrest of Zacarias Moussaoui and just before the hijackers begin to buy tickets for the flights they will hijack. [New York Times, 9/10/2002] CIA Director George Tenet will hint that Moussaoui’s arrest a few days earlier (on August 15 (see August 16, 2001)) may be connected to when the date of the attacks is picked. [US Congress, 6/18/2002] On the other hand, some terrorists appear to have made plans to flee Germany in advance of the 9/11 attacks on August 14, one day before Moussaoui’s arrest (see August 14, 2001).
August 20, 2001 and After: Key Justice Department Unit Not Consulted about Moussaoui Warrant Request
A key Justice Department unit, the Office of Intelligence and Policy Review (OIPR), is not consulted about a request to search Zacarias Moussaoui’s belongings. Although it is this office that would submit an application for a search warrant under the Foreign Intelligence Surveillance Act, the legal aspects of the application are discussed only with the National Security Law Unit, which is beneath the OIPR (see August 22-28, 2001). FBI officials discuss what they think the OIPR will want in a warrant application, but do not ask it directly. Sherry Sabol, an attorney in the lower National Security Law Unit, will later say that she would have contacted the OIPR to discuss a possible warrant application, if FBI headquarters agents had not withheld information from her (see August 22-28, 2001). When shown the relevant documentation for the Moussaoui case after 9/11, the OIPR’s general counsel will say he would have considered the application and, if submitted, he “would have tied bells and whistles” to a comment by Moussaoui’s imam that Moussaoui and an associate wanted to “go on jihad” (see August 17, 2001). [US Department of Justice, 11/2004, pp. 132-166, 182-4, 201 ] However, a memo from Attorney General John Ashcroft issued in May to improve the efficiency of the FISA process recommended communications between field offices, FBI headquarters, and the OIPR. In addition, the OIPR and the FBI should hold regular monthly meetings to discuss FISA warrants. It is unclear if such a meeting is held in the three weeks between Moussaoui’s arrest and 9/11. However, one of the people supposed to attend such meetings is Spike Bowman, chief of the National Security Law Unit, who is involved in the Moussaoui case (see August 28, 2001). [US Department of Justice, 5/18/2001 ]
August 21, 2001: Inmate Warns of Impending Attack in New York
Walid Arkeh, a Jordanian serving time in a Florida prison, is interviewed by FBI agents after warning the government of an impending al-Qaeda attack. He had been in a British jail from September 2000 to July 2001, and while there had befriended three inmates, Khalid al-Fawwaz, Adel Abdel Bary, and Ibrahim Eidarous. US prosecutors charge, “The three men ran a London storefront that served as a cover for al-Qaeda operations and acted as a conduit for communications between bin Laden and his network.” [Orlando Sentinel, 10/30/2002] Al-Fawwaz was bin Laden’s press agent in London, and bin Laden had called him over 200 times before al-Fawwaz was arrested in 1998. [Financial Times, 11/29/2001; Sunday Times (London), 3/24/2002] The other two had worked in the same office as al-Fawwaz (see Early 1994-September 23, 1998). All three had been indicted as co-conspirators with bin Laden in the August 1998 US embassy bombings. Arkeh tells the FBI that he had learned from these three that “something big [is] going to happen in New York City,” and that they call the 1993 attack on the WTC “unfinished business.” Tampa FBI agents determine that he had associated with these al-Qaeda agents, but nonetheless they do not believe him. According to Arkeh, one agent responds to his “something big” warning by saying: “Is that all you have? That’s old news.” The agents fail to learn more from him. On September 9, concerned that time is running out, a fellow prisoner will try to arrange a meeting, but nothing will happen before 9/11. The Tampa FBI agents will have a second interview with him hours after the 9/11 attacks, but even long after 9/11 they will claim that he cannot be believed. On January 6, 2002, the Tampa FBI will issue a statement: “The information [was] vetted to FBI New York, the Acting Special Agent in Charge of the Tampa Division and the United States Attorney for the Middle District of Florida. All agreed the information provided by this individual was vague and unsubstantiated… Mr. Arkeh did not provide information that had any bearing on the FBI preventing September 11.” [Orlando Sentinel, 1/6/2002; Orlando Sentinel, 10/30/2002] However, a different group of FBI agents will interview him in May 2002 and find his information credible (see May 21-22, 2002).
August 21, 2001-September 13, 2001: FBI and CIA Ask British about Moussaoui But Get No Answer until After 9/11
On August 21, the FBI’s legal attache in London hand-delivers a request for information about Zacarias Moussaoui to British officials. On August 24, the CIA tells the British that Moussaoui is a possible “suicide hijacker” who is involved in “suspicious 747 flight training.” The CIA asks for information on him on August 28. The FBI raises the matter with the British again on September 3 and again on September 5. Although the British do not respond to these requests until just after 9/11, French intelligence, which has been sharing information about Moussaoui with the British (see 1999), sends the FBI some information about Moussaoui’s activities and history in England (see August 22, 2001). Then, on September 13, 2001, the British supposedly learn new information that Moussaoui attended an al-Qaeda training camp in Afghanistan (see 1995-1998). The 9/11 Commission will conclude, “Had this information been available in late August 2001, the Moussaoui case would almost certainly have received intense and much higher-level attention.” A British official will complain, “We passed on all the relevant information [about Moussaoui] as soon as we obtained it.” [Guardian, 4/14/2004; 9/11 Commission, 7/24/2004, pp. 274-75] However, the British had Moussaoui under surveillance in 2000 (see Mid-2000-December 9, 2000), and appear to have failed to pass on any information about this surveillance or what it uncovered.
August 21-22, 2001: FBI Agents Finally Realize 9/11 Hijacker Almihdhar Is in US
An FBI agent detailed to the CIA’s bin Laden unit locates CIA cables saying that future 9/11 hijacker Nawaf Alhazmi entered the US in early 2000. The agent, Margaret Gillespie, then checks with the US Customs Service and discovers that another future 9/11 hijacker, Khalid Almihdhar, entered the US on July 4, 2001, and there is no record he has left the country. As there is “an imperative to find anyone affiliated with al-Qaeda if they [are] believed to be in the US,” Gillespie immediately contacts Dina Corsi, an FBI agent in its bin Laden unit. Gillespie, who has been examining the USS Cole bombing and al-Qaeda’s Malaysia summit for some time, will later say that when she learns of their arrival in the US, “it all clicks for me.” The Justice Department’s office of inspector general will find that Gillespie’s “actions on receipt of the information clearly indicate that she understood the significance of this information when she received it. She took immediate steps to open an intelligence investigation.” Gillespie and Corsi meet with Tom Wilshire, a CIA officer involved in the investigation (see August 22, 2001), and Almihdhar and Alhazmi are soon watchlisted (see August 23, 2001).
