On the 25th anniversary of September 11, the CIA released several dozen presidential daily briefs detailing intelligence gathered about Osama bin Laden and al-Qaida before the attacks. These documents reveal security analysts' tracking of Bin Laden’s movements, finances, and operations, including discussions of potential threats to US targets, hijackings, and biological weapons experimentation. The declassified files span from February 1998 through September 2001, with specific briefs highlighting concerns over attacks within the United States and against U.S. soil using unconventional tactics like chemical or biological agents.

Why this leaning score
This article does not take a side on a contested political
question, so it has no leaning score. That is an
answer rather than a gap: a match report or a rescue can be warmly
or critically written without being left or right, and scoring it
anyway is how approval of a subject gets recorded as a political
position.

The documents range from a February 1998 file – prepared for then president Bill Clinton – titled “Terrorists seeking WMD capability” and mentioning Bin Laden and other Islamic extremists – to a 12 September 2001 report in which a source indicated the attacks had been planned for two years and had also targeted the US Capitol.

An April 1998 document described the Taliban’s unwillingness to hand over Bin Laden, at the time seen as their “guest” in Afghanistan, noting their “gratitude for his assistance during the Soviet occupation” was making them “reluctant to alienate him by monitoring or controlling his activities”.

Briefers in July 1998 called it “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”.

Ladin → call → agents
Two months later, a briefer wrote that Bin Laden’s “preferred option is to strike the US on its own soil in Washington”, and that al-Qaida “may fly an explosive-packed airplane into a US city”.
Potential hijackings were also discussed in December 1998, when a briefer described how conspirators “had evaded security checks during a recent trial run at an unidentified New York airport”, and “some members of the Bin Ladin network have received hijack training”.
Other documents detail Bin Laden’s pursuit of materials for making “dirty bombs”, conventional weapons infused with radioactive material.

At that time – 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”, adding that the FBI was “conducting approximately 70 full field investigations throughout the US that it considers Bin Ladin-related”.

In the years immediately after the attacks, a bipartisan commission highlighted a lack of information-sharing among agencies such as the CIA and FBI, and issued recommendations that yielded new positions, including a centralized director of national intelligence, as well as the National Counterterrorism Center, which analyzes domestic and foreign terrorism information across different government branches.
