From The Hill:

Law enforcement authorities are investigating an anthrax scare at the offices of Rep. Jo Bonner (R) and several other Alabama lawmakers.

Bonner's offices were closed on Monday after each received suspicious letters, according to a spokesman for Bonner, while the offices of Rep. Bobby Bright (D) and Sens. Richard Shelby (R) and Jeff Sessions (R) were also targeted, according to the Associated Press. ...

The letters were received this morning, Bonner's spokesman said, and the letters have been turned over to law enforcement. The offices haven't yet begun to reopen.

The AP said that the powder in the envelopes has been confirmed as not being anthrax, though authorities are uncertain what the substance is. The AP also reported that federal investigators suspect the letters came from the same source.

UPDATE: Anthrax scares in Alabama cities

Per The Associated Press:

Envelopes containing white powder set off anthrax scares in five Alabama cities, shutting down two federal courthouses Monday and trapping a congressman in his office as authorities tested the substance. ...

"Each letter contained a small bag with a white powdery substance, and neither of these bags were opened," said Mike Lewis, a spokesman for Bonner.

The FBI and U.S. Postal Inspection Service said letters also were sent to the offices of U.S. Rep. Mike Rogers and U.S. Sens. Jeff Sessions and Richard Shelby in Montgomery. FBI spokeswoman Angela Tobon said all the letters sent to the lawmakers' offices appeared to be from a common source.

Two more letters were sent to the federal courthouse in Anniston, and another letter was found at a federal courthouse in Birmingham, where an employee doing extra work found the first envelope Sunday at the Robert Vance Federal Building.
