(CNN) - Nevada Gov. Jim Gibbons was recuperating early Wednesday after he was thrown off a horse, his spokesman said.
Gibbons was riding with his brother Tuesday afternoon near Pyramid Lake when the accident occurred, said spokesman Dan Burns.
The governor is an experienced rider but the horse had only been saddled for a month, Burns said.
Washington (CNN) - A domestic extremist group has sent letters to more than 30 U.S. governors demanding they resign, the Department of Homeland Security and the FBI said in an intelligence note.
The letters told the governors to vacate their posts within three days, the note said.
DHS and the FBI said there do not appear to be credible or immediate threats of violence attached to the letters.
The group behind the letters has a "Restore America Plan" that calls for the removal of any governor who fails to comply, the intelligence note said.
