James "Bo" Gritz, a former Green Beret colonel and leader of the so-called Patriot Movement, was hospitalized with an apparently self-inflicted gunshot wound.

Gritz was taken to Clearwater Valley Hospital in Orofino on Sunday afternoon, the Clearwater County Sheriff's Department said.A hospital spokeswoman would not give a condition for Gritz or even confirm he was a patient.

No details were released except that the incident involved Gritz, who had an apparently self-inflicted gunshot wound, and that an investigation was continuing.

Gritz, 59, is probably best known for his role as negotiator in the FBI siege on the Randy Weaver family in Ruby Ridge in 1992. He also briefly was a mediator in the Montana Freemen standoff in 1996.

Gritz ran for president in 1992 and is a leader of the so-called Patriot Movement, which rails against a purported United Nations-led "New World Order" and accuses the government of corruption and violence.
