(Burns, OR) -- The leader of an armed militia that has seized a federal building in eastern Oregon says he doesn't think the standoff will come to a violent end. Ammon Bundy appeared on the Fox News Channel's "The Kelly File," saying he's there to defend his freedom and liberty, and not to die. Bundy and a group took over a building at the Malheur National Wildlife Refuge after a protest over a prison sentence for a pair of ranchers convicted of arson. Harney County Sheriff David Ward is calling on the militia to vacate the premises.
