It has not been revealed when US intelligence begins monitoring bin Laden exactly, though the CIA was tailing him in Sudan by the end of 1991 (see February 1991- July 1992). But in late 1995 the FBI is given forty thick files on bin Laden from the CIA and NSA, mostly communications intercepts (see October 1995). The sheer amount of material suggests the surveillance had been going on for several years. Dan Coleman, an FBI agent working with the CIA’s bin Laden unit, will begin examining these files and finds that many of them are transcripts from wiretapped phones tied to bin Laden’s businesses in Khartoum, Sudan, where bin Laden lives from 1991 to 1996. [Miller, Stone, and Mitchell, 2002, pp. 148-149; Wright, 2006, pp. 242-244] CIA Director George Tenet will later comment, “The then-obscure name ‘Osama bin Laden’ kept cropping up in the intelligence traffic.… [The CIA] spotted bin Laden’s tracts in the early 1990s in connection with funding other terrorist movements. They didn’t know exactly what this Saudi exile living in Sudan was up to, but they knew it was not good.” [Tenet, 2007, pp. 100] The London Times will later report that in Sudan, “bin Laden used an $80,000 satellite phone and al-Qaeda members used radios to avoid being bugged…” [London Times, 10/7/2001] Bin Laden is mistaken in his belief that satellite phones cannot be monitored; a satellite phone he buys in 1996 will be monitored as well (see November 1996-Late August 1998).
October 1995: FBI Begins Investigating Bin Laden; CIA Already Monitoring Him
The FBI opens a case on Osama bin Laden. Dan Coleman and John Ligouri, members of the FBI’s Joint Terrorism Task Force (JTTF), are sent to the CIA Counterterrorist Center (CTC) to see what the CIA knows about bin Laden. “They were amazed by the amount of material – some forty thick files’ worth – that they found.… Most of the information consisted of raw, unfocused data: itineraries, phone records, associates lists, investment holdings, bank transfers.” The vast majority of the data comes from NSA electronic eavesdropping and most of it has not been properly analyzed (see Early 1990s). They find that the CTC has been conducting a vigorous investigation on Wadih El-Hage, bin Laden’s personal secretary. [Miller, Stone, and Mitchell, 2002, pp. 148-149] Coleman will go on to become the FBI’s biggest expert on bin Laden and will help start the bureau’s bin Laden unit. [Suskind, 2006, pp. 90] It is not known when the CIA or NSA began monitoring bin Laden or El-Hage.
October 1995: FBI and CIA Investigating Bin Laden’s Personal Secretary
In 1995, the FBI is given the CIA’s files on bin Laden, and they discover that the CIA has been conducting a vigorous investigation on Wadih El-Hage, bin Laden’s personal secretary and a US citizen (see October 1995). The FBI had already started investigating El-Hage in 1991 (see March 1991), and in 1993 they found out he had bought weapons for one of the 1993 WTC bombers (see Summer 1993). Thanks to the CIA files, the FBI learns that in early 1992 El-Hage moved to Sudan and worked there as bin Laden’s personal secretary. [PBS Frontline, 4/1999; Miller, Stone, and Mitchell, 2002, pp. 148-149] Then, in 1994, he moved to Nairobi, Kenya, and officially started running a bogus charity there called “Help Africa People.” [PBS Frontline, 4/1999; CNN, 10/16/2001] In fact, El-Hage is running an al-Qaeda cell that will later carry out the 1998 African embassy bombings. He stays in close contact with top al-Qaeda leaders. [PBS Frontline, 4/1999] Apparently El-Hage is under US surveillance in Kenya, or at least people he is calling are under surveillance. For instance, a phone call between El-Hage in Kenya and Ali Mohamed in California is recorded in late 1994 (see Late 1994).and there are many calls recorded between El-Hage and bin Laden in Sudan. FBI agent Dan Coleman will analyze all this information about El-Hage and eventually supervise a raid on his Kenya house in 1997 (see August 21, 1997). [Wright, 2006, pp. 242-244]
January 1996: Squad Uniting Prosecutors and FBI Agents Begins Focusing on Bin Laden
The Justice Department directs an existing unit called Squad I-49 to begin building a legal case against bin Laden. This unit is unusual because it combines prosecutors from the Southern District of New York, who have been working on bin Laden related cases, with the FBI’s New York office, which was the FBI branch office that dealt the most with bin Laden -related intelligence. Patrick Fitzgerald effectively directs I-49 as the lead prosecutor. FBI agent Dan Coleman becomes a key member while simultaneously representing the FBI at Alec Station, the CIA’s new bin Laden unit (February 1996) where he has access to the CIA’s vast informational database. [Lance, 2006, pp. 218-219] The other initial members of I-49 are: Louis Napoli, John Anticev, Mike Anticev, Richard Karniewicz, Jack Cloonan, Carl Summerlin, Kevin Cruise, Mary Deborah Doran, and supervisor Tom Lang. All are FBI agents except for Napoli and Summerlin, a New York police detective and a New York state trooper, respectively. The unit will end up working closely with FBI agent John O’Neill, who heads the New York FBI office. Unlike the CIA’s Alec Station, which is focused solely on bin Laden, I-49 has to work on other Middle East -related issues. For much of the next year or so, most members will work on the July 1996 crash of TWA Flight 800, because it crashed near New York and is suspected to have been carried out by Middle Eastern militants (July 17, 1996-September 1996). However, in years to come, I-49 will grow considerably and focus more on bin Laden. [Wright, 2006, pp. 240-241] After 9/11, the “wall” between intelligence collection and criminal prosecution will often be cited for the failure to stop the 9/11 attacks. But as author Peter Lance will later note, “Little more than ten months after the issuance of Jamie Gorelick’s ‘wall memo,’ Fitzgerald and company were apparently disregarding her mandate that criminal investigation should be segregated from intelligence threat prevention. Squad I-49… was actively working both jobs.” Thanks to Coleman’s involvement in both I-49 and the CIA’s Alec Station, I-49 effectively avoids the so-called “wall” problem. [Lance, 2006, pp. 220]
June 1996-April 1997: Highly Trusted Informant Exposes Al-Qaeda Secrets to US
Jamal al-Fadl, an al-Qaeda operative from al-Qaeda’s first meeting in the late 1980s until 1995, tells the US everything he knows about al-Qaeda. Before al-Fadl’s debriefings, US intelligence had amassed thick files on bin Laden and his associates and contacts. However, they had had no idea how the many pieces fit together. But an official says. “After al-Fadl, everything fell into place.” [Miller, Stone, and Mitchell, 2002, pp. 154-65] The New Yorker will later call al-Fadl “arguably the United States’ most valuable informant on al-Qaeda.” FBI agent Dan Coleman will later say on al-Fadl, “He’s been very, very important to us. When it comes to understanding al-Qaeda, he’s the Rosetta Stone.” FBI agent Mike Anticev will similarly say, “He spoke to us in great detail, and everything that he told us panned out.” CIA officials debrief al-Fadl for a month and a half. Then the CIA hands him, and transcripts of all their interviews with him, over to the FBI. [New Yorker, 9/11/2006] Coleman and US prosecutor Patrick Fitzgerald interrogate al-Fadl at a US military base in Germany for months. [Lance, 2006, pp. 261] Roughly between November 1996 and April 1997, al-Fadl tells the FBI about: 
The historical background of al-Qaeda. Al-Fadl was one of al-Qaeda’s founding members (see August 11-20, 1988). The structure of al-Qaeda and its leadership composition. Al-Qaeda’s objectives and direction. Its financial infrastructure and networks. Al-Fadl has extensive knowledge of this because he worked as an al-Qaeda financial officer (see December 1996-January 1997). Its connections and collaboration with other terrorist groups and supporters. Its activities against US soldiers in Somalia (see October 3-4, 1993). Its activities in Bosnia. Al-Fadl was sent there on several missions (see Autumn 1992 and Autumn 1992). The Al-Kifah Refugee Center, al-Qaeda’s most important charity front in the US. Al-Fadl worked there in the 1980s (see 1986-1993). Bin Laden’s efforts to acquire weapons of mass destruction. Al-Fadl was personally involved in an effort to buy uranium for al-Qaeda (see Late 1993). [9/11 Commission, 7/24/2004, pp. 479] Bin Laden’s plans to attack either inside the US or US embassies (see Late 1996).
Al-Fadl continues to help US intelligence until current day. For instance, in 2000, he will help US officials capture his brother-in-law, Mohammed Suliman al-Nalfi, who is said to be close to Ayman al-Zawahiri. Al-Nalfi will eventually be sentenced to ten years in prison in the US. Al-Fadl will have no knowledge of the 9/11 plot, but he will continue to identify captured al-Qaeda operatives after 9/11. [New Yorker, 9/11/2006] Interestingly, al-Fadl, a Sudanese citizen, will later claim that he worked with the Sudanese intelligence agency with the direct approval of bin Laden. [Day 2. United States of America v. Usama bin Laden, et al., 2/6/2001]
Late 1996: CIA Definitively Confirms Bin Laden Is Not Just Financier, but US Is Slow to Act
By late 1996, the CIA definitively confirms that Osama bin Laden is more of a leader of militants worldwide than just a financier of them. [US Congress, 7/24/2003] CIA Director George Tenet will later comment, “By 1996 we knew that bin Laden was more than a financier. An al-Qaeda defector [Jamal al-Fadl] told us that [bin Laden] was the head of a worldwide terrorist organization with a board of directors that would include the likes of Ayman al-Zawahiri and that he wanted to strike the United States on our soil” (see June 1996-April 1997). [Tenet, 2007, pp. 102] Yet the US will not take “bin Laden or al-Qaeda all that seriously” until after the bombing of US embassies in Africa in 1998. [Miller, Stone, and Mitchell, 2002, pp. 213] Dan Coleman, the FBI’s top al-Qaeda expert, helps interrogate al-Fadl in 1996 and 1997 (see June 1996-April 1997), and Coleman comes to the conclusion that the US is facing a profound new threat. But according to journalist Robert Wright, Coleman’s reports “met with little response outside a small circle of prosecutors and a few people in the [CIA and FBI] who took an interest…” Michael Scheuer, head of the CIA’s bin Laden unit, is interested, as is John O’Neill, who heads the New York FBI office that specializes in bin Laden cases. But O’Neill and Scheuer hate each other and do not cooperate. [Wright, 2006] Al-Fadl’s information will not turn into the first US indictment of bin Laden until June 1998 (see June 8, 1998).
August 21, 1997: US Raids Al-Qaeda Cell Member’s House but Fails to Stop Embassy Bombing Plot
Dan Coleman, an FBI agent working with Alec Station, the CIA’s bin Laden unit, has been examining transcripts from wiretapped phones connected to bin Laden’s businesses in Sudan (see Early 1990s). One frequently called number belongs to Wadih El-Hage, a US citizen who is later revealed to be bin Laden’s personal secretary. El-Hage often makes obvious and clumsy attempts to speak in code. The CIA comes to believe that El-Hage might be recruited as an agent. On this day, Coleman, two CIA agents, and a Kenyan police officer enter El-Hage’s house in Nairobi, Kenya, with a search warrant. The investigators interview El-Hage (who returned that day from visiting bin Laden in Afghanistan) and confiscate his computer. [Los Angeles Times, 10/14/2001; Wright, 2006, pp. 242-244] A large amount of incriminating evidence is discovered in El-Hage’s documents and computer files (see Shortly After August 21, 1997 and Shortly After August 21, 1997). El-Hage moves to the US, where he is interviewed by a grand jury, then let go (see September 24, 1997). He will be arrested shortly after al-Qaeda bombs the US embassy in Nairobi (see September 15, 1998). He will be sentenced to life in prison for his role in that attack. State Department officials will later strongly assert that while staffers at the US embassy in Kenya were told about the raid at the time, they were not told about any potential connection to al-Qaeda. However, US intelligence officials strongly assert that the embassy staff was frequently briefed about the bin Laden connection. [New York Times, 1/9/1999]
Shortly After August 21, 1997: US Discovers More Evidence about Al-Qaeda Kenya Cell, but Fails to Act
FBI agent Dan Coleman and other US investigators discover a number of revealing items in the raid on Wadih El-Hage’s house in Nairobi, Kenya (see August 21, 1997). It is already known that El-Hage is a member of an al-Qaeda Kenya cell and bin Laden’s former personal secretary. Items found include: A letter is found on El-Hage’s confiscated personal computer written by Fazul Abdullah Mohammed (a.k.a. Haroun Fazul), another member of the al-Qaeda Kenya cell who is living with El-Hage at the time. The letter was written a week before the raid. It refers to the “East African cell,” alludes to the cell’s role in attacking US soldiers in Somalia in 1993 (see Late 1992-October 1993 and 1993), explains that a cache of incriminating files was recently moved from El-Hage’s house and hidden, and says the members of the cell are “convinced one hundred percent” that they’re being monitored by intelligence agencies. It also talks about other operatives in the town of Mombasa, Kenya, and talks about the imminent arrival of “engineers” to help the cell. [New York Times, 1/9/1999; PBS Frontline, 4/1999; Miller, Stone, and Mitchell, 2002, pp. 204-205] Another document found on the same computer reveals that El-Hage was sent to Kenya by bin Laden to initiate a “new policy” for the Kenya cell and “prepare 300 activists.” Other members of the cell were advised “of the need to move families to a secure region before the ‘activism.’” It notes that other operatives have carried out an operation in the capital of Ethiopia (presumably the attempted assassination of Egyptian President Hosni Mubarak (see Shortly After June 26, 1995)) and adds, “There are a lot of explosions in the other cities, and the brothers are taking up these operations.” [New York Times, 1/22/2000] A genuine-looking Kenyan travel stamp is found, which could be used to make documents appear authentic. [New York Times, 1/22/2000] Other files reveal that El-Hage and an associate are fabricating false passports for operatives in the Caucasus, as well as for fighters in Somalia. [New York Times, 1/22/2000] Further documents show that El-Hage bought guns for bin Laden in Eastern Europe and was making frequent trips to Tanzania (the Kenya al-Qaeda cell will bomb the US embassy in Tanzania in 1998 (see 10:35-10:39 a.m., August 7, 1998). [Wright, 2006, pp. 244] Additionally, El-Hage’s address book is found, which provides many more leads (see Shortly After August 21, 1997). Yet, despite all this, no arrests are made and no urgent alarms are sounded. The wiretaps on the Kenya cell are actually stopped by the end of the month. [MSNBC, 12/4/2000] Crucial data about Fazul Abdullah Mohammed is found as well. US intelligence does look for him for a while. But he simply leaves Kenya for a few months and then returns, moving to another house in Nairobi and where he starts work on building bombs in May 1998. [MSNBC, 12/4/2000; Los Angeles Times, 10/14/2001; US Congress, 10/21/2003] Author Lawrence Wright who interviews Coleman will paraphrase Coleman’s thoughts at the time: “Al-Qaeda was up to something, but it was unclear what that was. In any case, it was certainly a low-end operation, and the exposure of [El-Hage’s] house in Nairobi had no doubt put an end to it.” [Wright, 2006, pp. 244]
Late August 1998: CIA Discovers ‘Rosetta Stone of Al-Qaeda’ but Doesn’t Share with FBI
CIA operatives kidnap Ahmad Salama Mabruk and two other members of Islamic Jihad outside a restaurant in Baku, Azerbaijan (see Late August 1998). This is part of a covert CIA program to arrest Islamic Jihad operatives around the world and send them to Egypt (see Summer 1995). [Wall Street Journal, 7/2/2002] Mabruk is the closest ally of Ayman al-Zawahiri, al-Qaeda’s number two leader. Mabruk’s laptop computer turns out to contain al-Qaeda organizational charts and vital information about Islamic Jihad members in Europe. FBI agent Dan Coleman later calls this “the Rosetta Stone of al-Qaeda.” However, the CIA will not turn this information over to the FBI. John O’Neill, head of the FBI’s New York office, tries to get around this by sending an agent to Azerbaijan to get copies of the computer files from the Azerbaijani government. When that fails, he persuades President Clinton to personally appeal to the president of Azerbaijan for the files. The FBI eventually gets the files, but the incident deepens the tensions between the CIA and FBI. [Wright, 2006, pp. 268-269] The US monitored 67 phone calls between bin Laden and Azerbaijan from 1996 to 1998 (see November 1996-Late August 1998). Presumably, many of these would have been to Mabruk. Mabruk is sent to Egypt and given a long prison sentence. [Wall Street Journal, 7/2/2002]
Late 1998: FBI Asks NSA to Pass on All Calls between Al-Qaeda Yemen Hub and US
The FBI asks the NSA to pass on all calls between an al-Qaeda communications hub in Yemen and the US. The hub, which is run by an operative named Ahmed al-Hada and was involved in the attacks on US embassies in East Africa (see Late August 1998), is a key al-Qaeda logistics center and intelligence gleaned from listening in on calls to and from it will help prevent some attacks (see August 4-25, 1998 and Late 1998-Early 2002). Dan Coleman, one of the FBI agents who places the request, will say, “anyone who called the Yemen number is white-hot, a top suspect.” However, the NSA will not inform the FBI of all calls between the hub and the US. [Suskind, 2006, pp. 94] In particular, two 9/11 hijackers will call the hub while they are in the US (see Early 2000-Summer 2001). However, the information will be withheld from the FBI and various explanations will be offered for this failure (see (Spring 2000), Summer 2002-Summer 2004, and March 15, 2004 and After).
