> Declassified CIA presidential briefs show that US leaders received repeated warnings from 1998 to September 2001 about Osama bin Laden and al-Qaeda’s plans and capabilities, including possible attacks inside the United States. The files trace the group’s networks, financing, weapons efforts and hijacking training, but add little about how the attacks were actually planned.
