On December 4, 1998, an item in President Clinton’s Presidential Daily Briefing (PDB) is titled, “Bin Laden Preparing to Hijack US Aircraft and Other Attacks.” The PDB says “Bin Laden and is allies are preparing for attacks in the US, including an aircraft hijacking to obtain the release of Sheikh Omar Abdul-Rahman, Ramzi Yousef, and Muhammad Sadiq ‘Awda. One source quoted a senior member of Al-Gama’a al-Islamiyya (IG) saying that, as of late October, the IG had completed planning for an operation in the US on behalf of bin Laden, but that the operation was on hold. A senior bin Laden operative from Saudi Arabia was to visit IG counterparts in the US soon thereafter to discuss options-perhaps including an aircraft hijacking.” The same source says bin Laden may implement plans to hijack US aircraft before the start of the Muslim holy month of Ramadan on December 20 and that two members of the operational team had evaded security checks in a recent trial run at a New York airport. A possible different source says that in late September, Mohammed Shawqui Islambouli, brother of the assassin of Egyptian President Anwar Sadat and described in the PDB as an IG leader, was planning to hijack a US airliner during the “next couple of weeks” to free Abdul-Rahman and other prisoners. The PDB also says that “some members of the bin Laden network have received hijack training, according to various sources, but no group directly tied to bin Laden’s al-Qaeda organization has ever carried out an aircraft hijacking. Bin Laden could be weighing other types of operations against US aircraft.” The PDB mentions other bin Laden related threats, including recent reports that the IG has obtained surface-to-air missiles and intends to move them from Yemen to Saudi Arabia to shoot down aircraft. [Washington Post, 7/18/2004; 9/11 Commission, 7/24/2004, pp. 128-130] The private intelligence group Stratfor will later say that, in addition to his ties with IG, Islambouli worked with bin Laden in the Maktab al-Khidamat charity front in Pakistan and is believed to have lived in Afghanistan in the 1990s as “part of the group of key Egyptian advisers surrounding bin Laden.” Islambouli will formally join with al-Qaeda in 2006. [Stratfor, 8/10/2006] In early 1998, the CIA ignored information from a recently retired CIA agent that claimed 9/11 mastermind Khalid Shaikh Mohammed was in a terrorist cell with Islambouli, both were experts on plane hijackings, and were planning to hijack planes (see Early 1998). Perhaps not coincidentally, on this same day, CIA Director George Tenet issues a “declaration of war” against al-Qaeda in a memo to the US intelligence community (see December 4, 1998). Also on this day, counterterrorism “tsar” Richard Clarke holds a meeting of his interagency Counterterrorism and Security Group (CSG) to discuss the threat. The group agrees that New York City airports should go on a maximum security alert that weekend and security should be boosted at other East Coast airports. The FBI, FAA, and New York City Police Department get versions of the PDB report. Later in December and again in January 1999 the source says the hijacking has been postponed because two operatives have been arrested in Washington or New York. But the FBI is unable to find any information to support the threat nor is it able to verify any arrests similar to what the source described, and the source remains mysterious. The high alert in New York airports is canceled by the end of January. [9/11 Commission, 7/24/2004, pp. 128-130] This PDB will be mentioned in President Bush’s famous August 6, 2001 PDB, but mentions that US officials “have not been able to corroborate” the plot (see August 6, 2001).
December 9, 1999: President Clinton Warned about Al-Qaeda Operatives Living in US
As an al-Qaeda millennium plot is broken up in Jordan (see November 30, 1999), attention is focused on the fact that two of the plotters were long time US residents. National Security Adviser Sandy Berger sends a memo to President Clinton about the two men, Raed Hijazi and Khalil Deek. Hijazi had lived in California and then moved to Boston to drive a taxi there for several years. The 9/11 Commission will say Berger tells Clinton was a naturalized US citizen who had “been in touch with extremists in the United States as well as abroad.” Later in the month, counterterrorism “tsar” Richard Clarke will warn Berger in an e-mail, “Foreign terrorist sleeper cells are present in the US and attacks in the US are likely.” [9/11 Commission, 7/24/2004, pp. 179, 501] Deek is arrested on December 11 (see December 11, 1999), but he will eventually be released without being charged (see May 2001). A few days later, Clarke authorizes a study that looks into Deek’s connections, but no action will be taken when it is discovered Deek’s next-door neighbor is still living in Anaheim, California, and running an al-Qaeda sleeper cell there (see December 14-25, 1999). Similarly, while Hijazi will be arrested overseas some months later (see September 2000), US intelligence seems oblivious to the other al-Qaeda operatives who have been his roommates and fellow taxi drivers in Boston (see June 1995-Early 1999 and October 2000). One of them, Nabil al-Marabh, will apparently go on to have a major role in the 9/11 plot (see for example January 2001-Summer 2001 and Early September 2001). Investigators will also fail to act on knowledge of financial transactions between Hijazi and three of the 9/11 hijackers (see Spring 2001).
2000: FBI Repeatedly Tells Clinton that Al-Qaeda Is Unable to Attack Inside US
In the wake of disrupting Ahmed Ressam’s millennium bomb plot at the end of 1999 and arresting his cohorts (see December 14, 1999)
(see December 15-31, 1999), US intelligence remains concerned that al-Qaeda sleeper cells remain in the US (see March 10, 2000). However, Clinton’s National Security Adviser Sandy Berger later claims that the FBI still repeatedly assures the Clinton White House that al-Qaeda lacks the ability to launch a domestic strike. [New York Times, 9/22/2002] He says, “Until the very end of our time in office, the view we received from the [FBI] was that al-Qaeda had limited capacity to operate in the US and any presence here was under surveillance.” No analysis is done before 9/11 to investigate just how big that presence might be. [Washington Post, 9/20/2002]
December 18, 2000: CIA Director Warns Clinton of Increased Risk that Al-Qaeda Could Attack in Coming Weeks
In a memo to President Clinton that is also widely distributed in the US intelligence community, CIA Director George Tenet warns: “The next several weeks will bring an increased risk of attacks on our country’s interests from one or more Middle Eastern terrorist groups… The volume of credible threat reporting has grown significantly in the past few months, particularly concerning plans by Osama bin Laden’s organization for new attacks in Europe and the Middle East.… Our most credible information on bin Laden activity suggests his organization is looking at US facilities in the Middle East, especially the Arabian peninsula, in Turkey and Western Europe. Bin Laden’s network is global however and capable of attacks in other regions, including the United States.” [Tenet, 2007, pp. 128-129] Just one day later, Clinton will brief incoming President Bush on the al-Qaeda threat (see December 19, 2000).
December 19, 2000: Clinton Tells Bush His Top Priority Should Be Bin Laden; Bush Says It’s Saddam Hussein Instead
President Clinton and President-Elect Bush meet for their “exit interview,” in a two-hour meeting. [CNN, 12/19/2000] Clinton gives Bush his list of his top five priorities. At the top of the list is dealing with Osama bin Laden. Clinton also discusses the tensions between Pakistan and India, who are threatening each other with nuclear strikes; the crisis in the Middle East between Israel and Palestine; he discusses North Korea; and he discusses Iraq and Saddam Hussein. Bush shakes Clinton’s hand after Clinton wraps up his presentation, and says, “Thanks for your advice, Mr. President, but I think you’ve got your priorities wrong. I’m putting Saddam at the top of the list.” [Moore, 3/15/2004, pp. 16-17] Just one day before, CIA Director George Tenet had warned Clinton that al-Qaeda could attack US interests in the next several weeks (see December 18, 2000). In 2003, Clinton will speak about the interview, saying that he recognized Bush felt the biggest security issues facing the US was Iraq and a national missile defense: “I told him that in my opinion, the biggest security problem was Osama bin Laden.” [Reuters, 10/16/2003]
January 20-September 10, 2001: President Bush Briefed on Al-Qaeda over 40 Times
National Security Adviser Condoleezza Rice later testifies to the 9/11 Commission that in the first eight months of Bush’s presidency before 9/11, “the president receive[s] at these [Presidential Daily Briefings] more than 40 briefing items on al-Qaeda, and 13 of those [are] in response to questions he or his top advisers posed.” [Washington Post, 4/8/2004] The content of the warnings in these briefings are unknown. However, CIA Director George Tenet claims that none of the warnings specifically indicates terrorists plan to fly hijacked commercial aircraft into buildings in the US. [New York Times, 4/4/2004] Counterterrorism “tsar” Richard Clarke will later emphasize, “Tenet on 40 occasions in… morning meetings mentioned al-Qaeda to the president. Forty times, many of them in a very alarmed way, about a pending attack.” [Vanity Fair, 11/2004] These briefings are normally given in person by CIA Director George Tenet, and are usually attended by Vice President Cheney and National Security Adviser Rice. In the Clinton administration, up to 25 officials recieved the PDB. But in the Bush adminisration before 9/11, this was sharply reduced to only six people (see After January 20, 2001). Other top officials have to make due with an Senior Executive Intelligence Brief generally released one day later, which is similar to the PDB but often contains less information (see August 7, 2001). [9/11 Commission, 7/24/2004, pp. 256, 533]
January 25, 2001-September 10, 2001: Counterterrorism ‘Tsar’ Clarke Unable to Talk to President Bush about Terrorism before 9/11
Counterterrorism “tsar” Richard Clarke submits a comprehensive plan to deal with al-Qaeda within days of President Bush’s inauguration (see January 25, 2001). He wants to meet with Bush directly to discuss it with him, but he is unable to do so before 9/11. Clarke will later recall, “I asked for a meeting with the president several times beginning, in fact, before [National Security Adviser] Rice even took office in the transition briefing. I said I have given this briefing to the vice president, I’ve given it to the secretary of state, I’ve given it now to you, I would like to give it to the president. And what I was told was I could brief the president on terrorism after the policy development process had been completed.” He does have one meeting with Bush before 9/11, but only to discuss cyber security because Clarke is planning to quit his current job to focus on that issue instead (see June 2001). When asked why he didn’t bring up al-Qaeda at that meeting, Clarke will reply, “Because I had been told by Dr. Rice and her deputy that this was a briefing on countering the cyber threats and not on al-Qaeda and that I would have my opportunity on al-Qaeda if I just held on, eventually they would get to it, probably in September.” [ABC News, 4/8/2004] The Bush administration had downgraded Clarke’s position in early January 2001 and he was no longer able to send memos directly to the president as he could during the Clinton administration (see January 3, 2001).
Early February 2001: Counterterrorism ‘Tsar’ Clarke Urges Vice President Cheney to Take Action Against Al-Qaeda
Counterterrorism “tsar” Richard Clarke briefs Vice President Cheney about the al-Qaeda threat. He urges decisive and quick action against al-Qaeda. Cheney soon visits CIA headquarters for more information about al-Qaeda. However, at later high-level meetings Cheney fails to bring up al-Qaeda as a priority issue. [Time, 8/12/2002; Clarke, 2004, pp. 227-30]
February 6, 2001: White House Told of New Rise in Terrorist Threats
A Senior Executive Intelligence Brief (SEIB), entitled “Sunni Terrorist Threat Growing,” is sent to top White House officials. It indicates a heightened threat of Sunni extremist attacks, particularly in the Middle East and Europe, against US facilities and personnel. (Bin Laden is the most wanted Sunni extremist by this time.) The briefing states this is considered the most significant spike in threat reporting since the Millennium. The SEIB is usually released one day after the corresponding President Daily Briefing is given to the president and contains similar content (see January 20-September 10, 2001), so it is probable Bush is given this warning. Based on this warning, a terrorist threat advisory will be shared throughout the US intelligence community on March 30, and the FBI will send out a warning to its field offices in April (see April 13, 2001). [US District Court of Eastern Virginia, 5/4/2006, pp. 1

April 19-20, 2001: President Bush Warned ‘Bin Laden Planning Multiple Operations’
On April 19, 2001, the interagency Counterterrorism Security Group (CSG) chaired by counterterrorism “tsar” Richard Clarke discusses recent reports that al-Qaeda leader Abu Zubaida is planning an attack. The next day, a Senior Executive Intelligence Brief (SEIB) with the title “Bin Laden Planning Multiple Operations” is sent to top White House officials. The New York Times will later report that President Bush and Vice President Cheney were among those who received this warning. Since SEIBs are usually based on previous days’ President Daily Briefings, President Bush probably learned about this report on April 19 (see January 20-September 10, 2001). [New York Times, 4/18/2004; 9/11 Commission, 7/24/2004, pp. 255; US District Court of Eastern Virginia, 5/4/2006, pp. 2 ]
