A Pennsylvania National Guardsman is in jail after allegedly threatening to kill Vice President Mike Pence before his visit to a Flight 93 memorial service.

22-year-old William Robert Dunbar, of Berlin, PA, was charged Saturday with disorderly conduct and terroristic threats.

Richland Township, PA Police allege that Dunbar was on duty at the Army National Guard Training Center when he said, "If someone pays me enough money, I will kill the vice president."

Witnesses said they contacted commanding officers after they heard Dunbar make the threat twice.

Police said Dunbar was taken to Conemaugh Memorial Medical Center for a mental evaluation and then to a county prison in lieu of $250,000 bond.

Court documents don't list an attorney and a listed phone number for Dunbar couldn't be found Monday.
