Creepy Letters to 30 Governors Spook FBI Pols told to leave office in 3 days or they will be removed By Kevin Spak, Newser Staff Posted Apr 2, 2010 10:37 AM CDT 33 comments Comments The seal of the FBI hangs in the Flag Room at the bureau's headquarters in this file photo. (Getty Images) (Newser) – The FBI has warned police around the country that there may be violence in the coming days inspired by ominous letters sent by an extremist group. Thirty sitting governors have received letters telling them that if they don’t leave office within 3 days they will be removed, according to an intelligence note, reports the AP. The letters don’t threaten any violence, but the FBI fears others will use their message “as a justification for violence or other criminal acts.” Recipients of the letter include Michigan's Jennifer Granholm, whose office called the letter "non-threatening," and Louisiana's Bobby Jindal. The letters come from a group calling itself the Guardians of the free Republics, which says it intends to “restore America” by peacefully dismantling parts of the government. The FBI says group members consider themselves “sovereign citizens,” who believe they are free from duties of ordinary Americans, like paying taxes and needing a license to drive.
