The warnings

“Bin Ladin Determined To Strike in US”

The August 6 brief, the summer of threats and what the President was told

RECORD / AT A GLANCE

Partly true

The President was warned that bin Laden wanted to strike inside the United States and that the FBI saw activity consistent with hijacking preparations. The brief did not give a date, a place or a method. The Commission found the summer’s warnings never produced a domestic mobilization.
