Colorado Gov. Bill Ritter is among state leaders across the country receiving threatening letters from an extremist group.
Megan Castle, Ritter's spokeswoman, said Friday that the letter received by Ritter has been turned over to the local FBI office.
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.
