Several dozen presidential briefing documents were declassified on the 25th anniversary of the Sept. 11 attacks, detailing intelligence gathered on Osama bin Laden and al‑Qaida in the years leading up to the hijackings, according to a report adapted from the Associated Press and published by Headline USA.
What was released
The Central Intelligence Agency described the move as the agency’s single largest release of declassified presidential daily briefs (PDBs), the highly classified updates prepared for senior U.S. leaders. The source report attributed a statement calling the release “an act of exceptional transparency” to CIA Director John Ratcliffe.
Early warnings, 1998–1999
A February 1998 PDB prepared for President Bill Clinton was titled “Terrorists seeking WMD capability,” mentioning bin Laden and other Islamic extremists, per the documents cited by the report.
An April 1998 brief described the Taliban’s unwillingness to hand over bin Laden—then considered their “guest” in Afghanistan—citing “gratitude for his assistance during the Soviet occupation” and reluctance to “monitor or control his activities.”
In July 1998, briefers wrote it was “plausible that Bin Ladin places a high priority on conducting attacks in the United States” and noted his “interest in conducting attacks with chemical and biological agents.”
Two months later, a PDB said bin Laden’s “preferred option is to strike the US on its own soil in Washington,” adding that al‑Qaida “may fly an explosive‑packed airplane into a US city.”
By December 1998, potential hijackings were on briefers’ radar: a PDB described conspirators who “had evaded security checks during a recent trial run at an unidentified New York airport,” and said “some members of the Bin Ladin network have received hijack training.”
Dirty‑bomb and bio‑agent fears
Other briefs cited in the report said bin Laden pursued materials for “dirty bombs”—conventional explosives laced with radioactive material. By June 1999, his operatives had conducted experiments with explosives to “increase their energy output,” according to intelligence officials summarized in the declassified materials.
Early 2001 PDBs prepared for President George W. Bush noted “experimentation by crude means to make and deploy biological agents.”
Al‑Qaida activity inside the U.S. before 9/11
A report one month before the attacks indicated bin Laden’s commitment “to conduct terrorist attacks in the US,” citing the 1998 embassy bombings as evidence that “he prepares operations years in advance and is not deterred by setbacks.”
In August 2001, officials wrote 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,” and noted the FBI was “conducting approximately 70 full field investigations throughout the US that it considers Bin Ladin‑related.”
Redactions, limits, and added context
Many documents were redacted to protect sources and identifying information. The report said the materials did not appear to break new ground on the planning of the attacks or on officials’ understanding of how they unfolded.
In the years after 9/11, a bipartisan commission cited failures of information sharing among agencies including the CIA and FBI, leading to the creation of positions and bodies such as a centralized director of national intelligence and the National Counterterrorism Center, according to the report.
Additional records from the National Archives
Asked for comment on the release, the White House pointed to another batch of records published the same day by the National Archives. That set, the report noted, included interviews with national security officials from the Clinton and Bush administrations and was produced by the 2002–2004 commission that investigated the attacks.
