Count Minnesota Gov. Tim Pawlenty among the 30 governors who received a letter from an extremist group demanding they leave office within three days or be removed.
Pawlenty says Friday that he received one of the letters, but he's not overly alarmed by it. He says he gets all sorts of "interesting" mail so it's not out of the norm.
He declined to say if extra precautions were taken as a result of the letter, saying the administration does not publicly comment about his security.
An intelligence note obtained by The Associated Press is warning police officials that the group's call to remove dozens of sitting governors may encourage others to act out violently.
A group that calls itself the Guardians of the free Republics has a plan to "restore America" by peacefully dismantling parts of the government, according to its Web site.
A spokeswoman says Wisconsin Gov. Jim Doyle is also among the governors who have received letters from an anti-government group calling for him to leave office.
