Twenty-five years after nearly three thousand lives were lost in a single morning, declassified presidential briefings confirm what many long suspected: the warnings were there, carried in careful bureaucratic language across two administrations, naming names and describing rehearsals. The release of seventy-one presidential daily briefs spanning 1998 to 2001 does not resolve the question of culpability so much as it deepens the older, harder question of how knowledge becomes action — and why, so often, it does not.
Declassified files show Clinton, Bush got repeated warnings of bin Laden hijack plots
The machinery of intelligence was running, the dots were visible.
So these documents show both Clinton and Bush got warnings about hijackings. How specific were they really?
Specific enough that the CIA was naming the tactic—hijacking commercial jets—and identifying that bin Laden's people had trained for it and even done a dry run at a New York airport. That's not vague.
But the December 1998 brief says "no group directly tied to bin Ladin's al-Qa'ida organization has ever carried out an aircraft hijacking." So they knew the threat existed in theory, but it hadn't happened yet.
Right. Which is why the August 2001 brief is so striking—it says the FBI found suspicious activity consistent with hijacking preparations happening inside the U.S. right then.
And how many investigations were actually underway?
About seventy field investigations the FBI believed were related to bin Laden, according to the briefing Bush got weeks before the attacks.
But we don't know from these documents how many of those seventy were actually tracking the specific people who carried out 9/11. That's the gap.
So the warnings existed, but did anyone connect them to what actually happened?
That's the question these documents raise but don't answer. They show what was known. They don't show what was done with it.
And they don't show whether the people running those seventy investigations had the resources, the coordination, or the authority to act on what they were finding.
So transparency about the warnings, but not necessarily about the response.
Exactly.
The Pulse
- Seventy-one declassified briefings now confirm that both the Clinton and Bush administrations received repeated, specific CIA warnings that al-Qaeda operatives were training to hijack commercial aircraft and strike American cities.
- The urgency embedded in these documents is striking — one 1998 brief described a successful trial run by bin Laden-linked operatives who evaded security at a New York airport, three years before the attacks.
- By August 2001, the FBI was running approximately seventy field investigations tied to bin Laden's network, and a presidential brief explicitly noted suspicious activity consistent with hijacking preparations inside the United States.
- Despite visible infrastructure spread across New York, California, Texas, Michigan, and Florida, and warnings that bin Laden sought to retaliate against Washington, the intelligence never cohered into prevention.
- CIA Director John Ratcliffe framed the release as an act of transparency and tribute, part of a broader declassification effort that has also touched the Kennedy and King assassination files.

On the twenty-fifth anniversary of the September 11 attacks, the Trump administration released seventy-one presidential daily briefs covering the years 1998 through the summer of 2001 — documents that reveal, in the government's own words, how much was known before nearly three thousand people died.
Both Bill Clinton and George W. Bush received repeated CIA warnings that Osama bin Laden's network was actively planning to seize commercial aircraft and use them as weapons against American cities. A December 1998 brief confirmed that bin Laden's operatives had undergone hijack training. Months earlier, another briefing had warned that bin Laden's preferred target was Washington, D.C., and that his network — already responsible for the East Africa embassy bombings — might attempt to fly an explosives-laden plane into an American city.
The threat was not merely theoretical. Operatives tied to bin Laden had already conducted a trial run, successfully evading security checks at an unidentified New York airport three years before the attacks. Their stated aim was to use hijacked flights as leverage to free imprisoned extremists, including Shaykh 'Umar 'Abd al-Rahman and Ramzi Yousef. Meanwhile, U.S. intelligence had identified bin Laden's support network operating across multiple states — New York, California, Texas, Michigan, and Florida.
The warnings continued into the final weeks before the attacks. On August 6, 2001, Bush received a brief stating that the FBI had detected patterns of suspicious activity inside the United States consistent with hijacking preparations, including recent surveillance of federal buildings in New York. Weeks later, another brief noted that the FBI was running approximately seventy field investigations it believed were connected to bin Laden.
CIA Director John Ratcliffe announced the release as both a tribute to those killed and an act of governmental transparency — part of a broader declassification effort that has also included files on the assassinations of President Kennedy, Robert Kennedy, and Martin Luther King Jr. The documents do not answer every question. But they make plain that the machinery of warning was running, and that the picture it was drawing, though visible, remained unfinished until it was too late.
On Friday, the Trump administration released seventy-one presidential daily briefs that laid bare what American intelligence agencies knew, and when they knew it, about al-Qaeda's intentions to hijack commercial aircraft and strike U.S. targets. The documents span from 1998 through the summer of 2001—a window of warning that touched two presidencies and ended three months before the attacks.
Bill Clinton and George W. Bush both received repeated alerts from the CIA that Osama bin Laden's network was actively planning to seize large jets and use them as weapons against American cities. The intelligence was specific and alarming. One December 1998 presidential daily brief noted that members of bin Laden's organization had undergone hijack training, though it cautiously added that no group directly connected to al-Qaeda had yet carried out an aircraft hijacking. The same document suggested bin Laden might be considering other types of operations against U.S. aircraft. Months earlier, in September 1998, another briefing warned that bin Laden's preferred target was Washington, D.C., and that his network—the same group responsible for the East Africa embassy bombings—might attempt to fly an explosives-laden plane into an American city.
The plotters had already conducted what amounted to a dress rehearsal. According to the declassified files, operatives tied to bin Laden had successfully evaded security checks during a trial run at an unidentified New York airport three years before the September 11 attacks. Their goal, the documents indicate, was to use hijacked flights as leverage to secure the release of imprisoned extremists, including Shaykh 'Umar 'Abd al-Rahman and Ramzi Yousef.
Throughout 1998, U.S. intelligence agencies tracked bin Laden's movements and the network supporting him. They identified associates and sympathizers operating across multiple states—New York, California, Texas, Michigan, and Florida. The infrastructure was there, visible to American intelligence, spread across the country.
The warnings did not stop when Clinton left office. On August 6, 2001, just over a month before the attacks, Bush received a presidential daily brief informing him that the FBI had uncovered patterns of suspicious activity inside the United States consistent with preparations for hijackings or other attacks. That same briefing noted recent surveillance of federal buildings in New York. The document stated plainly that al-Qaeda members, including some who held U.S. citizenship, had lived in or traveled to America for years, and that the group maintained a support structure capable of facilitating attacks. It also reminded Bush that after American missile strikes on bin Laden's base in Afghanistan in 1998, bin Laden had told his followers he wanted to retaliate in Washington.
Weeks before September 11, another daily brief for Bush reported that the FBI was conducting approximately seventy field investigations throughout the country that it believed were connected to bin Laden. The machinery of American intelligence was running, the dots were visible, and yet the picture they formed remained incomplete.
CIA Director John Ratcliffe announced the release of the documents in a statement, framing the declassification as a way to honor those killed on September 11 and the CIA officers who died in the subsequent fight against terrorism. The Trump administration has positioned this broader declassification effort—which has also included files on the assassinations of President Kennedy, Robert Kennedy, and Martin Luther King Jr.—as an exercise in transparency about what the government knew and when.
