Update 2:03: For the record, Perdue's office confirms that she's not resigning, the N&O's Ben Niolet reports.
The office of N.C. Gov. Bev Perdue received a letter this week from an anti-government group that's written to governors around the country demanding they leave their posts, The Associated Press reports.
Perdue communications director Chrissy Pearson said today that a letter from the Guardians of the free Republics came to Perdue's constituent services office Tuesday or Wednesday.
The letter was forwarded to Perdue's security detail. Pearson couldn't give details about how Perdue's security officers responded except to say the threats are taken very seriously.
The FBI expects governors in all 50 states to receive the letters and has told police nationwide the group's call to remove governors from office could provoke violence.
Perdue was in Charlotte today for President Barack Obama's visit.
