FBI warns of extremist violence

The FBI is warning police across the country that an anti-government group's call to remove governors from office could provoke violence by others. A group that calls itself the Guardians of the free Republics wants to "restore America" by peacefully dismantling parts of the government, according to its Web site. As of Wednesday, more than 30 governors had received letters saying if they don't leave office within three days they will be removed, according to an internal intelligence note by the FBI and the Department of Homeland Security. The note was obtained by The Associated Press. Investigators do not see threats of violence in the group's message, but fear the broad call for removing top state officials could lead others to act out violently. Governors whose offices reported receiving the letters included Jennifer Granholm of Michigan, Bobby Jindal of Louisiana, Chet Culver of Iowa and Jim Gibbons of Nevada. Screening machines for visitors and packages were added to the main entrance to the Nevada Capitol as a precaution after Gibbons received one of the letters. "We're not really overly concerned, but at the same time we don't want to sit back and do nothing and regret it," Deputy Chief of Staff Lynn Hettrick said.
