A New Hampshire county chairman for the Trump campaign once threatened to kill his police boss and rape the cop's wife and children, according to stunning allegations from authorities.

Jonathan Stone, a former New Hampshire police officer, has been a part of Trump's campaign in the state since 2016 when he gifted Trump an inscribed AR-15 assault rifle. Stone is the owner of gun store Black Op Arms in Claremont, New Hampshire.

Stone was ousted from the Claremont Police Force 10 years ago after allegedly threatening to kill the department chief — and his colleagues — and rape the chief's wife and kids in retaliation for his suspension over an alleged relationship with a high school girl, according to a report from a police internal affairs investigation, which was obtained by the New Hampshire Center for Public Information Journalism.

The report was released following a lawsuit by the center demanding the information.

Stone, now a second-term state representative, was appointed as Trump's campaign chair in Sullivan County last summer.

He did not immediately return messages seeking comment.

Trump's New Hampshire state campaign chair, Stephen Stepanek, told the HuffPost he didn't know about Stone's alleged background until reading news accounts of it.

"He's been a Trump supporter for a long time, and he's been a state representative, and he had, as far as we were concerned, what looked like a great background," said Stepanek.

As for Stone's future with the campaign, "We haven't made any decisions yet," he added.

He told HuffPost that any action will likely be up to Trump's top campaign aides at Mar-a-Lago.
