Federal authorities announced charges Monday against a New Hampshire man they say sent threatening text messages to presidential campaigns and targeted one candidate with a promise to “blow his brains out.”

Tyler Anderson was charged with transmitting a threat through interstate means.

The FBI said Mr. Anderson lashed out after getting a text message last Friday from one of the presidential campaigns advertising an event in Portsmouth on Monday.

“Great, another opportunity for me to blow [redacted] brains out!” Mr. Anderson texted back, according to the FBI. He also added: “I’m going to kill everyone who attends and then [expletive] their corpses.”

The FBI didn’t reveal the name of the candidate, but the timing of the event tracks with one GOP presidential hopeful Vivek Ramaswamy had planned for a Portsmouth diner Monday morning.

FBI Agent Adam Howe, in a court filing, said Mr. Anderson also lashed out at another candidate after receiving a text about an upcoming appearance.

“Fantastic, now I know where to go so I can blow that bastard’s head off!” the texted reply said.

“Hope you have the stamina for a mass shooting!” the text continued. “And then I’m gonna [expletive] [redacted] corpse.”

Authorities tracked Mr. Anderson down by his phone number. They said the campaign he threatened had his information on file, and it was corroborated by records from local police and the phone company.

When they served a search warrant, that’s when they found the threatening messages to the second campaign.

Mr. Anderson, 30, a Dover resident, has an initial court appearance scheduled for Monday afternoon.
