U.S. Attorney Booth Goodwin on Monday announced the arrest of Steven Anthony Major, 49, of Barboursville, W.Va., after Major allegedly made at least three phone calls to Manchin's Capitol Hill and Charleston offices last week.
An affidavit from FBI Special Agent Jason Bollinger said Major identified himself during the phone calls while threatening Manchin to stay out of his home state.
"You a dead man you don't [expletive] with me," Major allegedly said, according to Bollinger's affidavit. "Your kids and your wife are done. [Manchin] and his family going to have bullets in their brains."
The report said law enforcement was able to trace one of the calls to a cell phone registered to Major.
Major was scheduled to appear before a judge Monday afternoon and he faces up to 10 years in prison if convicted.
