A Senior Executive Intelligence Brief (SEIB), entitled “Sunni Terrorist Threat Growing,” is sent to top White House officials. It indicates a heightened threat of Sunni extremist attacks, particularly in the Middle East and Europe, against US facilities and personnel. (Bin Laden is the most wanted Sunni extremist by this time.) The briefing states this is considered the most significant spike in threat reporting since the Millennium. The SEIB is usually released one day after the corresponding President Daily Briefing is given to the president and contains similar content (see January 20-September 10, 2001), so it is probable Bush is given this warning. Based on this warning, a terrorist threat advisory will be shared throughout the US intelligence community on March 30, and the FBI will send out a warning to its field offices in April (see April 13, 2001).
