OKLAHOMA CITY -- Gov. Brad Henry's office confirms it received a letter this week from an anti-government group that sent notes to more than 30 governors seeking their removal.

Henry spokesman Paul Sund said Friday the letter was received Wednesday and handed over to the governor's security team and federal authorities.

Sund says he couldn't discuss details surrounding the letter. He said the office was warned by federal authorities before it arrived.

A group calling itself Guardians of the Free Republics says on its Web site that it wants to "restore America" by peacefully dismantling parts of the government.

Federal investigators say they do not see threats of violence in the group's message, but fear it could lead others to act out violently.
