July 26, 2001: CBS News reports that Attorney General Ashcroft has stopped flying commercial airlines due to a threat assessment, but "neither the FBI nor the Justice Department ... would identify [to CBS] what the threat was, when it was detected or who made it." [CBS, 7/26/01] FTW "Ashcroft demonstrated an amazing lack of curiosity when asked if he knew anything about the threat. 'Frankly, I don't,' he told reporters." [San Francisco Chronicle, 6/3/02] It is later reported that he stopped flying in July based on threat assessments made on May 8 and June 19. In May 2002 its claimed the threat assessment had nothing to do with al-Qaeda, but Ashcroft walked out of his office rather than answer questions about it. [AP, 5/16/02] The San Francisco Chronicle concludes, "The FBI obviously knew something was in the wind ... The FBI did advise Ashcroft to stay off commercial aircraft. The rest of us just had to take our chances." [San Francisco Chronicle, 6/3/02] CBS's Dan Rather later says of this warning: "Why wasn't it shared with the public at large?" [Washington Post, 5/27/02]
