In 1999, a Moroccan named Hassan Dabou infiltrated al-Qaeda for the Moroccan intelligence agency. He was sent to Afghanistan, posing as an Islamic radical on the run from the Moroccan government. While there, he was able to grow close to bin Laden. He heard bin Laden repeatedly vent his anger at the failure of the World Trade Center bombing in 1993 (see February 26, 1993). Bin Laden was “very disappointed” that the towers did not fall. Dabou heard that bin Laden had planned “something spectacular” involving “large scale operations in New York in the summer or fall of 2001.” Moroccan intelligence passed this information to US. Around this time, US intelligence is so interested that they call Dabou to Washington to report on this information in person. Dabout makes the trip in secret, but apparently his cover is blown and he is unable to go back and gather more intelligence. Dabou is still in Washington cooperating with US intelligence agents when 9/11 occurs. After 9/11 he will remain in Washington, get a new identity, and continue to work with US intelligence.

August 2001: Persian Gulf Informant Gives Ex-CIA Agent Information About ‘Spectacular Terrorist Operation’
Former CIA agent Robert Baer is advising a prince in a Persian Gulf royal family, when a military associate of this prince passes information to him about a “spectacular terrorist operation” that will take place shortly. He is given a computer record of around 600 secret al-Qaeda operatives in Saudi Arabia and Yemen. The list includes ten names that will be placed on the FBI’s most wanted terrorists list after 9/11. He is also given evidence that a Saudi merchant family had funded the USS Cole bombing on October 12, 2000, and that the Yemeni government is covering up information related to that bombing. At the military officer’s request, he offers all this information to the Saudi Arabian government. However, an aide to the Saudi defense minister, Prince Sultan, refuses to look at the list or to pass the names on (Sultan is later sued for his complicity in the 9/11 plot in August 2002). Baer also passes the information on to a senior CIA official and the CIA’s Counter Terrorism Center, but there is no response or action. Portions of Baer’s book describing his experience wil be blacked out, having been censored by the CIA. [Baer, 2002, pp. 55-58; Financial Times, 1/12/2002]
Early August 2001: Alleged Informant with 9/11 Foreknowledge Arrested in Turkey and Let Go
Al-Qaeda operative Luai Sakra is reportedly arrested by Turkish intelligence in Turkey and then let go. It will later appear that Sakra was an informant for the CIA, Turkish intelligence, and Syrian intelligence before 9/11. He appears to have begun working for the CIA and Turkish intelligence in 2000 (see 2000). Sakra will later claim to have been arrested and quickly released twice by Turkish intelligence. It seems the first time was in 2000 and this was the second time. [Der Spiegel (Hamburg), 8/24/2005] It would make sense that he was released at this time if he was a secret informant for Turkey. It will later come to light that Sakra had some foreknowledge of the 9/11 attacks and warned Syrian intelligence about them one day before the attacks (see September 10, 2001). But it is not known if he used this arrest to warn Turkish intelligence and/or the CIA as well.
Early August 2001: CIA’s Concern over Planned Bin Laden Strikes inside US Are Heightened
The CIA has “developed general information a month before the [9/11] attacks that heightened concerns that Osama bin Laden and his followers were increasingly determined to strike on US soil,” the Associated Press will later report. A CIA official will affirm, “There was something specific in early August that said to us that [bin Laden] was determined in striking on US soil.” [Associated Press, 10/3/2001] Further details about this information will remain unknown. However, the October 2001 article mentioning it could be describing an early, incomplete account of the CIA-produced Presidential Daily Briefing (PDB) entitled “Bin Laden Determined to Strike in US” from August 6, 2001 (see August 6, 2001). The full title of that PDB will be made public in May 2002 (see May 15, 2002), and the full text of it will be made public in April 2004 (see April 11, 2004).
Summer 2001: IAEA Scientist: US ‘Wants to Attack’ Iraq
After CIA analyst Joe Turner’s presentation to UN atomic energy scientists (see Late July 2001), one of the scientists calls David Albright, a nuclear physicist who runs the Washington-based Institute for Science and International Security, and warns him that the “people across the river [i.e., the CIA] are trying to start a war. They are really beating the drum. They want to attack.” [Isikoff and Corn, 2006, pp. 37]
August 2, 2001: Former Turkish Spy Warns the CIA about the Planned 9/11 Attacks, but Is Ignored
Mehmet Eymur, a retired Turkish intelligence official, allegedly alerts the CIA to the imminent 9/11 attacks, but his warning is ignored. Eymur, the former head of the counterterrorism department of the Turkish National Intelligence Organization, will claim this in a book released in 2019. Eymur, who now lives in the US, has learned of the planned terrorist attacks from a Turkish drug dealer called Mustafa. He contacted the CIA yesterday and said he needed to have a meeting regarding an important issue, and the CIA agreed to see him at his home. Today, therefore, he is visited by two CIA officials. One of them is a woman he already knows; the other is a man he has never met before. Mustafa is waiting at a nearby hotel, at Eymur’s request, in case the CIA officials want to interview him. During his meeting with the CIA officials, Eymur passes on the information Mustafa has given to him. However, according to Eymur, they are uninterested in it. He will suggest in 2019 that the information might have prevented the 9/11 attacks, stating: “Forty days after the meeting, one of the deadliest terror attacks in the history of the United States occurred.… If Mustafa was taken seriously, maybe this incident would have been prevented.” American intelligence agencies contact Eymur after 9/11, the retired spy will write in his 2019 book, and he consequently puts the CIA and the FBI in touch with Mustafa. However, Mustafa will subsequently tell him that his meetings with the two agencies were unproductive due to language issues. [Demiroren News Agency, 6/14/2019]
August 4-5, 2001: Phoenix Memo Agent Vets Bush PDB, Fails to Add Relevant Information, Does Not Contact Phoenix Office
The CIA officers who draft a presidential daily briefing (PDB) item given to George Bush on August 6 (see August 6, 2001) ask an FBI agent for additional information and also to review a draft of the memo, but she does not provide all the additional information she could. The 9/11 Commission will refer to the FBI agent as “Jen M,” so she is presumably Jennifer Maitner, an agent with the Osama bin Laden unit at FBI headquarters. The purpose of the memo is to communicate to the president the intelligence community’s view that the threat of attacks by bin Laden is both current and serious. But Maitner fails to add some important information that she has: around the end of July, she was informed of the Phoenix memo, which suggests that an inordinate number of bin Laden-related Arabs are taking flying lessons in the US (see July 10, 2001). She does not link this to the portion of the memo discussing aircraft hijackings. Responsibility for dealing with the Phoenix memo is formally transferred to her on August 7, when she reads the full text. The finished PDB item discusses the possibility bin Laden operatives may hijack an airliner and says that there are “patterns of suspicious activity in this country consistent with preparations for hijackings.” It is unclear whether the draft PDB item Maitner reviews contains this information. However, if it does, it apparently does not inspire her to take any significant action on the memo before 9/11, such as contacting the agents in Phoenix to notify them of the preparations for hijackings (see July 27, 2001 and after). The PDB will contain an error, saying that the FBI was conducting 70 full field investigations of bin Laden-related individuals (see August 6, 2001), but this error is added after Maitner reviews the draft, so she does not have the opportunity to remove it.

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).
August 6, 2001: President Bush Tells CIA Regarding Bin Laden Warning, ‘You’ve Covered Your Ass, Now’
According to journalist and author Ron Suskind, just after a CIA briefer presents President Bush with the later infamous PDB (Presidential Daily Briefing) item entitled “Bin Laden Determined to Strike in US” (see August 6, 2001), Bush tells the briefer, “You’ve covered your ass, now.” This account is from Suskind’s 2006 book The One Percent Doctrine, which is based largely on anonymous accounts from political insiders. In the book, after describing the presentation of the PDB, Suskind will write: “And, at an eyeball-to-eyeball intelligence briefing during this urgent summer, George W. Bush seems to have made the wrong choice. He looked hard at the panicked CIA briefer. ‘All right,’ he said. ‘You’ve covered your ass, now.’” [Suskind, 2006, pp. 2; Washington Post, 6/20/2006]
Between August 6 and September 10, 2001: ’Bin Laden Determined to Strike in US’ Memo Is Not Acted Upon
The 9/11 Commission will later state that after the now famous “bin Laden Determined to Strike in US” memo is given to President Bush on August 6, 2001 (see August 6, 2001), “We have found no indication of any further discussion before September 11 among the president and his top advisers of the possibility of a threat of an al-Qaeda attack in the United States.” [Newsweek, 4/28/2005] 9/11 Commissioner Bob Kerrey will later state to CNN,“[B]y the way, there’s a credible case that the president’s own negligence prior to 9/11 at least in part contributed to the disaster in the first place.… [I]n the summer of 2001, the government ignored repeated warnings by the CIA, ignored, and didn’t do anything to harden our border security, didn’t do anything to harden airport country, didn’t do anything to engage local law enforcement, didn’t do anything to round up INS and consular offices and say we have to shut this down, and didn’t warn the American people. The famous presidential daily briefing on August 6, we say in the report that the briefing officers believed that there was a considerable sense of urgency and it was current. So there was a case to be made that wasn’t made.… The president says, if I had only known that 19 Islamic men would come into the United States of America and on the morning of 11 September hijack four American aircraft, fly two into the World Trade Center, one into the Pentagon, and one into an unknown Pennsylvania that crashed in Shanksville, I would have moved heaven and earth. That’s what he said. Mr. President, you don’t need to know that. This is an Islamic Jihadist movement that has been organized since the early 1990s, declared war on the United States twice, in ‘96 and ‘98. You knew they were in the United States. You were warned by the CIA. You knew in July they were inside the United States. You were told again by briefing officers in August that it was a dire threat. And what did you do? Nothing, so far as we could see on the 9/11 Commission.” [CNN, 11/8/2004]
