A Senior Executive Intelligence Brief (SEIB) sent to top White House officials on May 26, 2001, is entitled, “Bin Laden Network’s Plans Advancing.” Further details are unknown. The New York Times will later report that President Bush and Vice President Cheney were among those who received this warning. SEIBs are typically summaries of the previous days’ President Daily Briefings (see January 20-September 10, 2001), so it is probable Bush is given this warning on May 25.
