Apr. 11—A Butler County man threatened to kill President Donald Trump, immigration officers and other federal-level advisors, writing on YouTube that he would “assassinate [Trump] myself,” according to federal charges unsealed Friday.
“Nah, we just need to start killing people, Trump, Elon, all the heads of agencies Trump appointed, and anyone who stands in the way,” Shawn Monper allegedly wrote in a YouTube comment in mid-February.
Mr. Monper, 32, is charged with four counts of making threats against federal officials and federal law enforcement officers.
He was taken into custody by federal agents and Butler Township police officers Wednesday at his home in Butler — less than five miles from where a South Hills man tried to assassinate Trump in July.
Under the username “Mr Satan,” Mr. Monper alleged in comments that he’d been stockpiling firearms and ammunition since the November general election. “Eventually [I’m] going to do a mass shooting,” he allegedly wrote on March 13.
Authorities said Mr. Monper was issued a gun permit about a week after Trump’s Jan. 20 inauguration.
Other comments attributed to Mr. Monper targeted Immigration and Customs Enforcement officers. A few days after his mass shooting remark, he allegedly wrote: “ICE are terrorist people, we need to start killing them.”
“Rest assured that whenever and wherever threats of assassination or mass violence occur, this Department of Justice will find, arrest, and prosecute the suspect to the fullest extent of the law,” U.S. Attorney General Pam Bondi said in a statement.
Butler County became the focus of the world last year when a 20-year-old man tried to assassinate Trump during a July campaign rally at the Butler Farm Show grounds. The shots, fired from the roof of a building just outside the event’s secure perimeter, wounded Trump and two spectators and killed a man who dove to shield his family.
