Threatening letters sent to Governors

MONTGOMERY, AL (WSFA)- Governor Bob Riley's staff is checking to see if he received a letter from the anti-government group "Guardians of the Free Republics."

So far, 30 governors have confirmed receiving the letters telling them to either step down from office or be removed.

The FBI is warning police that although the letters do not contain treats of violence, it's possible the message could incite others to commit violent acts.
