BIRMINGHAM, Ala. (AP) -- Envelopes containing white powder have prompted at least seven anthrax scares across Alabama. The FBI said Monday that five letters were sent to the offices of senators or congressmen. One was sent to U.S. Rep. Jo Bonner's office in Mobile, and another to his office in Foley. Letters were also sent to the offices of U.S. Rep. Bobby Bright of Montgomery, U.S. Sen. Jeff Sessions and U.S. Sen. Richard Shelby.
