On September 11, 2026, the CIA released 71 declassified President's Daily Briefs (PDBs) related to the events surrounding the September 11, 2001 terrorist attacks. This marks the largest public release of such intelligence products connected to 9/11. The documents provide a detailed look at the evolving understanding of al-Qa'ida and the warnings about Usama Bin Ladin's plans, despite limited and often unclear intelligence at the time. The release follows a comprehensive declassification effort initiated under former President Donald Trump, aimed at increasing transparency around one of the nation's most sensitive intelligence publications. CIA Director John Ratcliffe emphasized that this release honors those who lost their lives on 9/11 and the officers who have since worked to prevent further attacks. The newly available documents offer the public unprecedented access to the intelligence community's analysis during a critical period in U.S. history.
