Al-Qaeda operative Ahmed Ressam is arrested in Port Angeles, Washington, attempting to enter the US with components of explosive devices. One hundred and thirty pounds of bomb-making chemicals and detonator components are found inside his rental car. He subsequently admits he planned to bomb Los Angeles International Airport on December 31, 1999. [New York Times, 12/30/2001] Alert border patrol agent Diana Dean stops him; she and other agents nationwide had been warned recently to look for suspicious activity. Ressam’s bombing would have been part of a wave of attacks against US targets over the New Year’s weekend (see December 15-31, 1999). He is later connected to al-Qaeda and convicted.

April 18, 2001: FAA Warns Airlines About Middle Eastern Hijackers
The FAA sends a warning to US airlines that Middle Eastern militants could try to hijack or blow up a US plane and that carriers should “demonstrate a high degree of alertness.” The warning stems from the April 6, 2001, conviction of Ahmed Ressam over a failed plot to blow up Los Angeles International Airport during the millennium celebrations. This warning expires on July 31, 2001. [Associated Press, 5/18/2002] This is one of 15 general warnings issued to airlines in 2001 before 9/11 (see January-August 2001), but it is more specific than usual. [CNN, 3/2002; CNN, 5/17/2002]
May 30, 2001: FBI Is Warned of Major Al-Qaeda Operation in the US Involving Hijackings, Explosives, and/or New York City
Ahmed Ressam is convicted in the spring of 2001 for attempting to bomb the Los Angeles International Airport (see December 14, 1999). Facing the likelihood of life in prison, he starts cooperating with authorities in an attempt to reduce his sentence. On this day, he details his experiences in al-Qaeda training camps and his many dealings with top al-Qaeda deputy Abu Zubaida. According to FBI notes from Ressam’s interrogation, Zubaida asked Ressam to send him six original Canadian passports to help Zubaida “get people to America” (see May 2001 and May 2001). Zubaida “wanted an operation in the US” and talked about the need to get explosives into the US for this operation, but Ressam makes it clear this was a separate plot from the one he was involved with. Notes from this day further explain that Ressam doesn’t know if any explosives made it into the US because once an operation is initiated, operators are not supposed to talk about it to anyone. [Calgary Herald, 4/3/2002; Newsweek, 4/28/2005] Zubaida told this to Ressam in 1999, but also indicated that he is willing to wait a year or more to make sure the plot comes to fruition successfully. [Tenet, 2007, pp. 146]
Similarity to 9/11 Attacks – There’s no concrete evidence that Ressam knows any detail of the 9/11 attacks. [Newsweek, 4/28/2005] However, Fox News will later report that roughly around this time Ressam testifies “that attack plans, including hijackings and attacks on New York City targets, [are] ongoing.” [Fox News, 5/17/2002] Questioned shortly after 9/11, Ressam will point out that given what he’s already told his US interrogators, the 9/11 attacks should not be surprising. He notes that he’d described how Zubaida talked “generally of big operations in [the] US with big impact, needing great preparation, great perseverance, and willingness to die.” Ressam had told of “plans to get people hired at airports, of blowing up airports, and airplanes.” [Newsweek, 4/28/2005]
Sharing the Warning – The CIA learns of this warning in June. [Tenet, 2007, pp. 146] Ressam will repeat some of this in a public trial in July (see July 8, 2001). Apparently, the FBI also waits until July to share the information from this debriefing with most other intelligence agencies, the INS, Customs Service, and the State Department. Ressam’s warnings will first be mentioned to Bush in his now famous August 6, 2001 briefing (see August 6, 2001), but as Newsweek will note, “The information from Ressam that was contained in [Bush’s] PDB [is] watered down and seem[s] far more bland than what the Algerian terrorist was actually telling the FBI.” Zubaida’s second plot will be boiled down to one sentence in the PDB: “Ressam also said that in 1998 Abu Zubaida was planning his own US attack.” [Newsweek, 4/28/2005]
August 6, 2001: Bush Receives Briefing Titled ‘Bin Laden Determined to Strike in US’
President Bush receives a classified presidential daily briefing (PDB) at his Crawford, Texas ranch indicating that Osama bin Laden might be planning to hijack commercial airliners. The PDB provided to him is entitled, “Bin Laden Determined to Strike in US.” The entire briefing focuses on the possibility of terrorist attacks inside the US. [New York Times, 5/15/2002; Newsweek, 5/27/2002] The analysts who drafted the briefing will say that they drafted it on the CIA’s initiative (see July 13, 2004), whereas in 2004 Bush will state that he requested a briefing on the topic due to threats relating to a conference in Genoa, Italy, in July 2001, where Western intelligence agencies believed Osama bin Laden was involved in a plot to crash an airplane into a building to kill Bush and other leaders (see April 13, 2004). The analysts will later explain that they saw it as an opportunity to convey that the threat of an al-Qaeda attack in the US was both current and serious. [9/11 Commission, 7/24/2004, pp. 260] The existence of this briefing is kept secret, until it is leaked in May 2002, causing a storm of controversy (see May 15, 2002). While National Security Adviser Condoleezza Rice will claim the memo is only one and a half pages long, other accounts state it is 11 1/2 pages instead of the usual two or three. [New York Times, 5/15/2002; Newsweek, 5/27/2002; Die Zeit (Hamburg), 10/1/2002] A page and a half of the contents will be released on April 10, 2004; this reportedly is the full content of the briefing. [Washington Post, 4/10/2004] The briefing, as released, states as follows (note that the spelling of certain words are corrected and links have been added): 
Clandestine, foreign government, and media reports indicate bin Laden since 1997 has wanted to conduct terrorist attacks in the US (see December 1, 1998). Bin Laden implied in US television interviews in 1997 and 1998 that his followers would follow the example of World Trade Center bomber Ramzi Yousef and “bring the fighting to America” (see May 26, 1998). After US missile strikes on his base in Afghanistan in 1998, bin Laden told followers he wanted to retaliate in Washington, according to a -REDACTED-service (see December 21, 1998). An Egyptian Islamic Jihad (EIJ) operative told -REDACTED- service at the same time that bin Laden was planning to exploit the operative’s access to the US to mount a terrorist strike. The millennium plotting in Canada in 1999 may have been part of bin Laden’s first serious attempt to implement a terrorist strike in the US. Convicted plotter Ahmed Ressam has told the FBI that he conceived the idea to attack Los Angeles International Airport himself (see December 14, 1999), but that bin Laden lieutenant Abu Zubaida encouraged him and helped facilitate the operation. Ressam also said that in 1998 Abu Zubaida was planning his own US attack (see Late March-Early April 2001 and May 30, 2001). Ressam says bin Laden was aware of the Los Angeles operation. Although bin Laden has not succeeded, his attacks against the US Embassies in Kenya and Tanzania in 1998 (see 10:35-10:39 a.m., August 7, 1998) demonstrate that he prepares operations years in advance and is not deterred by setbacks. Bin Laden associates surveyed our embassies in Nairobi and Dar es Salaam as early as 1993 (see Late 1993-Late 1994), and some members of the Nairobi cell planning the bombings were arrested and deported in 1997. Al-Qaeda members—including some who are US citizens—have resided in or traveled to the US for years, and the group apparently maintains a support structure that could aid attacks (see January 25, 2001). Two al-Qaeda members found guilty in the conspiracy to bomb our embassies in East Africa were US citizens (see September 15, 1998), and a senior EIJ member lived in California in the mid-1990s (see November 1989 and September 10, 1998). A clandestine source said in 1998 that a bin Laden cell in New York was recruiting Muslim-American youth for attacks (see October-November 1998). “We have not been able to corroborate some of the more sensational threat reporting, such as that from a [REDACTED] service in 1998 saying that bin Laden wanted to hijack a US aircraft to gain the release of ‘Blind Sheikh’ Omar Abdul-Rahman and other US-held extremists” (see 1998, December 4, 1998, and May 23, 2001). [9/11 Commission, 7/24/2004, pp. 223] According to the Washington Post, this information came from a British service. [Washington Post, 5/18/2002] Nevertheless, FBI information since that time indicates patterns of suspicious activity in this country consistent with preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York (see May 30, 2001). The FBI is conducting approximately 70 full-field investigations throughout the US that it considers bin Laden-related (see August 6, 2001). CIA and the FBI are investigating a call to our embassy in the UAE in May saying that a group or bin Laden supporters was in the US planning attacks with explosives (see May 16-17, 2001). [9/11 Commission, 7/24/2004, pp. 223]
In retrospect, the briefing is remarkable for the many warnings that apparently are not included (see for instance, from the summer of 2001 prior to August alone: May 2001, June 2001, June 12, 2001, June 19, 2001, Late Summer 2001, July 2001, July 16, 2001, Late July 2001, Late July 2001, Summer 2001, June 30-July 1, 2001, July 10, 2001, and Early August 2001). According to one account, after the PDB has been given to him, Bush tells the CIA briefer, “You’ve covered your ass now” (see August 6, 2001).
Incredibly, the New York Times later reports that after being given the briefing, Bush “[breaks] off from work early and [spends] most of the day fishing.” [New York Times, 5/25/2002] In 2002 and again in 2004, National Security Adviser Rice will incorrectly claim under oath that the briefing only contained historical information from 1998 and before (see May 16, 2002 and April 8, 2004).
12:04 p.m. September 11, 2001: Los Angeles Airport Evacuated
Los Angeles International Airport, the original destination of three of the aircraft hijacked in the morning’s terrorist attacks, is evacuated except for essential personnel. [Associated Press, 9/11/2001; CNN, 9/12/2001] Officials closed the airport at 9:25 a.m., but now police start evacuating it. For hours, heavily armed agents and bomb-sniffing dogs patrol the terminals. Dozens of Los Angeles Police Department officers and FBI agents search through the airport. A few areas are scrutinized with particular care, such as around a suspicious parcel in Terminal 4, where American Airlines flights usually arrive and take off. However, no bombs are found. [Los Angeles Times, 9/12/2001] While security is heightened at many US airports, the security precautions are particularly high at the Los Angeles and San Francisco airports (see 12:15 p.m. September 11, 2001), since these were the intended destinations of the four hijacked aircraft. [Associated Press, 9/11/2001; Los Angeles Times, 9/12/2001]
