Zalmay Khalilzad is appointed Special Assistant to the President and Senior Director for Gulf, Southwest Asia and Other Regional Issues on the National Security Council. Khalilzad was an official in the Reagan and George H. W. Bush administrations. During the Clinton years, he worked for Unocal. [US Department of State, 2001; Independent, 1/10/2002] He previously worked under Deputy Defense Secretary Paul Wolfowitz and helped him write a controversial 1992 plan for US world domination.(see March 8, 1992) [New York Times, 3/23/2003] He was a member of the neoconservative think tank Project for the New American Century. The Asia Times notes, “It was Khalilzad—when he was a huge Taliban fan—who conducted the risk analysis for Unocal (Union Oil Company of California) for the infamous proposed $2 billion, 1,500 kilometer-long Turkmenistan-Afghanistan-Pakistan [TAP] gas pipeline.” [Asia Times, 12/25/2003] After 9/11, he will be appointed as special envoy to Afghanistan (see January 1, 2002) and then US ambassador to Afghanistan (see November 2003).
May 24, 2001: Canadian Cell Said to Be Planning Attack against US
An anonymous caller tells US intelligence about a terrorist cell in Canada that might be planning an attack against the US. [9/11 Commission, 7/24/2004, pp. 256]
May 24-27, 2001: 9/11 Hijacker Alshehhi Goes to Vegas, Believes He Is Followed
9/11 hijacker Marwan Alshehhi takes a three-day trip to Las Vegas, and will later say he was followed on the trip. One of the hijackers’ associates, Ramzi bin al-Shibh, will later say in a 2002 interview that Alshehhi felt he was followed on a flight from New York to California by “security officers.” Bin al-Shibh will also say that fellow hijacker Ziad Jarrah felt he was followed on a similar flight (see June 7-10, 2001). 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar have also been concerned about possibly having been followed on a flight to the US (see January 15, 2000 and Mid-July 2000). [Fouda and Fielding, 2003, pp. 135] After arriving in New York from Florida and spending the night there, Alshehhi flies from New York to Las Vegas via San Francisco. He spends all but one night in Las Vegas at the St. Louis Manor hotel. He is clearly remembered by staff, who recall his face, manners, and that he was once visited by another man of Middle Eastern descent. He returns via the same route. [Las Vegas Review-Journal, 10/31/2001; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 53-4 
; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 3, 19 ] Several other hijackers also travel to Vegas (see May 24-August 14, 2001).
May 24-August 14, 2001: 9/11 Hijackers Make Several Unexplained Trips to Vegas
Several of the 9/11 hijackers make trips to Las Vegas and the west coast over the summer: 
May 24-27: Marwan Alshehhi flies to Vegas (see May 24-27, 2001); June 7-10: Ziad Jarrah takes a trip to Vegas (see June 7-10, 2001); June 28-July 1: Mohamed Atta takes his first trip to Vegas, flying from Fort Lauderdale to Boston and then, the next day, to Las Vegas via San Francisco with United Airlines. He stays there three nights, then returns to Boston via Denver, and flies to New York the next day; July 31-August 1: Waleed Alshehri flies from Fort Lauderdale to Boston and then takes American Airlines flight 195 to San Francisco the next day. After spending a night at the La Quinta Inn, he returns to Miami via Las Vegas; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 1-2, 16, 18 ; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006, pp. 55-7 ] August 1: Actor James Woods sees four people he will later suspect are hijackers, including individuals he believes to be Khalid Almihdhar and Hamza Alghamdi, on a transcontinental flight (see August 1, 2001). Abdulaziz Alomari is reported to try to get into the cockpit on a different flight from Vegas on the same day (see August 1, 2001); August 13-14: Atta, Hani Hanjour, and Nawaf Alhazmi all fly to Vegas, possibly meeting some other hijackers there (see August 13-14, 2001).
Nawaf Alhazmi and Khalid Almihdhar also made frequent car trips to Las Vegas from San Diego, where they lived in 2000. [Los Angeles Times, 9/1/2002; McDermott, 2005, pp. 192] The reason for these trips is never definitively determined, although there will be speculation the hijackers are casing aircraft similar to those they will hijack on 9/11. The 9/11 Commission will comment, “Beyond Las Vegas’s reputation for welcoming tourists, we have seen no credible evidence explaining why… the operatives flew to or met in Law Vegas.” [9/11 Commission, 7/24/2004, pp. 242, 248] After 9/11, it will be reported that the hijackers may use these cross-country flights to take pictures of airline cockpits and check out security at boarding gates. During the flights, the hijackers apparently take notes, watch the crews, and even videotape them. There are some reports that two, or perhaps more, of the hijackers sit in “jumpseats” in the pilot’s cabin, a courtesy extended by airlines to other pilots, during the surveillance flights (see Summer 2001) and on the day of 9/11 itself (see November 23, 2001). [Boston Globe, 11/23/2001; Associated Press, 5/28/2002] There are reports that the hijackers drink alcohol, gamble, and frequent strip clubs while they are in Las Vegas. For example, according to a dancer named “Samantha,” Marwan Alshehhi stares up at her blankly while she “undulate[s] her hips inches from his face” and only gives her $20, although he is a “light drinker.” [San Francisco Chronicle, 10/4/2001; Newsweek, 10/15/2001]
Late May, 2001: CIA Officer Passes Three Malaysia Summit Photographs to FBI, but Fails to Mention Some Important Details
Tom Wilshire, a CIA officer on loan to the FBI, obtains three photographs from the surveillance of al-Qaeda’s Malaysia summit (see January 5-8, 2000), and passes them to Dina Corsi, an agent with the FBI’s bin Laden unit. Corsi learned of the photographs’ existence following a discussion with CIA officer Clark Shannon. Although Wilshire does not have a “substantive conversation” with Corsi about the photos, he does identify hijacker Khalid Almihdhar in one of them, and says Almihdhar traveled from Sana’a, Yemen, to Dubai, United Arab Emirates, and then Kuala Lumpur, Malaysia, in early January 2000. However, Wilshire omits to mention that Almihdhar has a US visa, his associate hijacker Nawaf Alhazmi has traveled to the US, or another associate, Khallad bin Attash, has been identified in the photos. He also does not say why the photos were taken. Author Lawrence Wright will later say the photos are passed because Wilshire wants to know what the FBI knows. The CIA says it thinks the photos may show Fahad al-Quso, an al-Qaeda operative involved in the USS Cole bombing. Corsi understands that the photos are “not formally passed” to the FBI, but are only for limited use at a forthcoming meeting. Therefore, only limited information about them is provided at the meeting, causing a disagreement (see June 11, 2001). However, Wilshire will later say that Corsi could give the photos to the FBI, but the FBI could not then give them to a foreign government (note: the photos had been provided to a foreign government five months previously, so this restriction is meaningless). [US Department of Justice, 11/2004, pp. 286-7, 293-4 ; New Yorker, 7/10/2006 ] Other pictures of the summit are available to the CIA, and there is even video footage (see February 2000 and Mid-May 2001), but these are not shared with the FBI or widely discussed.
May 25-26, 2001: President Bush Is Told Bin Laden May Be Hinting about New Attack
A Senior Executive Intelligence Brief (SEIB) sent to top White House officials on May 26, 2001, is entitled, “Bin Laden Network’s Plans Advancing.” Further details are unknown. The New York Times will later report that President Bush and Vice President Cheney were among those who received this warning. SEIBs are typically summaries of the previous days’ President Daily Briefings (see January 20-September 10, 2001), so it is probable Bush is given this warning on May 25. [9/11 Commission, 7/24/2004, pp. 255; US District Court of Eastern Virginia, 5/4/2006, pp. 2 ]
May 26, 2001: 9/11 Hijacker Almihdhar Enters Saudi Arabia, Reportedly Tracked by Saudi Authorities
9/11 hijacker Khalid Almihdhar enters Saudi Arabia on a flight from Sana’a, Yemen. [Bamford, 2008, pp. 64] Almihdhar is on the terrorist watch list there (see 1997), and his passport contains an indicator the Saudi authorities use to track terrorists (see April 6, 1999), so the Saudis presumably register his arrival. Almihdhar likely visits the monitored Yemen hub at this time, since it is in Sana’a and his wife, baby, and other family live at the hub (see (May 26, 2001)).
May 26, 2001: 9/11 Hijacker Almihdhar Probably Stays in Closely Monitored Yemen Hub House Yet Again
Future 9/11 hijacker Khalid Almihdhar probably visits the closely monitored al-Qaeda communications hub in Yemen again. While it will not be reported that he is at the hub at this time, it is known that he flies from Sana’a, Yemen, to Saudi Arabia on May 26, 2001 (see May 26, 2001), and the Yemen hub is in Sana’a. [Bamford, 2008, pp. 64] Furthermore, Almihdhar’s wife, his recently born baby, and other family members live in the hub (which is run by his father-in-law Ahmed al-Hada). It would seem highly likely he would not pass through Sana’a without visiting his family. Almihdhar stayed at the hub for around a month in June 2000 (see (Mid-June-Mid-July 2000)) and then visited it again in February 2001 (see February 2001). Details of Almihdhar’s travels are unclear, but he may have traveled to Afghanistan via Iran later in February (see February 2001). He is in the United Arab Emirates and Malaysia in June 2001. [9/11 Commission, 7/24/2004, pp. 237] Each time Almihdhar visits the hub presents a great opportunity for the CIA and NSA, because they have been closely monitoring the hub for years. Phone calls to and from the hub, including ones made by Almihdhar and other 9/11 hijackers, are intercepted, rooms in the building are bugged, and spy satellites record visitors (see Late August 1998, Late 1998-Early 2002, and Early 2000-Summer 2001). Based on information gained from monitoring this house, the CIA and local intelligence services mounted a major operation against Almihdhar, other 9/11 hijackers, and several more al-Qaeda operatives in December 1999 and January 2000, when they were followed around the Middle East and South Asia and monitored during an al-Qaeda summit in Malaysia (see December 29, 1999, January 2-5, 2000, and January 5-8, 2000). So presumably US intelligence should be aware of this visit to the hub and who Almihdhar is, but what exactly is known and who may know it will not be made public.
May 29, 2001: FBI Agent O’Neill Tells a Colleague that More Al-Qaeda Attacks Will Happen
John O’Neill, special agent in charge of the FBI’s national security division in New York, tells FBI agent Steve Gaudin that more al-Qaeda attacks are going to occur. [Graff, 2011, pp. 259] Today, a jury convicts four men for their involvement in the bombings of the US embassies in Kenya and Tanzania in August 1998 (see 10:35-10:39 a.m., August 7, 1998 and February-July 2001). [CNN, 5/29/2001] O’Neill sat in on the closing arguments in the trial and after the verdict is given, he draws Gaudin aside. He puts his arm around the agent and tells him: “I’m sending you to a language school in Vermont. You’re gonna learn Arabic.” [Wright, 2006, pp. 339] “The case is over,” Gaudin protests, but O’Neill tells him, “No, there’s more coming.” [Graff, 2011, pp. 259] “You know this fight ain’t over,” O’Neill explains. Referring to Mohamed al-Owhali, one of the men convicted for his role in the embassy bombings, he continues: “What did al-Owhali tell you? He said, ‘We have to hit you outside so they won’t see us coming on the inside.’” [Wright, 2006, pp. 339] (Al-Owhali told Gaudin in 1998: “We have a plan to attack the US, but we’re not ready yet. We need to hit you outside the country in a couple of places so you won’t see what is going on inside. The big attack is coming. There’s nothing you can do to stop it.” [Wright, 2006, pp. 279] ) O’Neill is “the FBI’s top expert on al-Qaeda and Osama bin Laden,” according to New York magazine. [New York Magazine, 12/17/2001] According to journalist and author Murray Weiss, he has, since 1995, told any official in Washington, DC, who will listen that he is “sure bin Laden would attack on American soil.” [Weiss, 2003, pp. 360]
May 29, 2001: Counterterrorism ‘Tsar’ Clarke Asks for More to Be Done to Stop Expected Al-Qaeda Attacks
Counterterrorism “tsar” Richard Clarke suggests to National Security Adviser Rice that she ask CIA Director George Tenet what more the US can do to stop al-Qaeda leader Abu Zubaida from launching “a series of major terrorist attacks.” It is believed these attacks will probably be directed at Israeli targets, but possibly on US facilities. Clarke writes to Rice and her deputy, Stephen Hadley, “When these attacks occur, as they likely will, we will wonder what more we could have done to stop them.” [9/11 Commission, 7/24/2004, pp. 256]
