Attorney General John Ashcroft was urged in May 2001 by his top security experts not to fly aboard commercial aircraft because of personal threats on his life, not out of fears about terrorist hijackings, the Justice Department said. The department moved quickly to quell suggestions that Ashcroft, who routinely flies aboard a small jet operated by the FBI, took precautions for his own safety in the months before Sept. 11 based on warnings of any threats involving Usama bin Laden or the Al Qaeda terrorist network. Ashcroft declined to discuss the issue while visiting ... with Bulgarian justice officials in his office. Ashcroft walked from the room without comment when a reporter asked about it. An FBI security review after Ashcroft took office recommended that the attorney general eschew flying on commercial planes whenever possible, citing nonspecific threats against Ashcroft's life. Since July 2001, Ashcroft has typically flown aboard an FBI jet or aboard other jets leased by U.S. agencies, although he occasionally has traveled on commercial flights.
