Shawn Monper, 32, of Butler, Pennsylvania, pleaded guilty in federal court to threatening to assassinate President Donald Trump and other U.S. officials. The Justice Department confirmed the plea on Monday, stating Monper admitted to two counts of threatening to assault and murder officials with the intent to impede their duties.
Monper was arrested on April 9, 2025, after an FBI investigation into threats posted on YouTube under the username "Mr Satan." The FBI linked the account to Monper's home in Butler following a tip on April 8, 2025. His threats, made between January 15 and April 5, included statements about assassinating Trump, killing ICE agents, and planning a mass shooting.
In one post, Monper wrote, "Nah, we just need to start killing people, Trump, Elon [Musk], all the heads of agencies Trump appointed, and anyone who stands in the way." He also referenced obtaining firearms and ammunition since Trump's inauguration, stating he had bought "several guns" and stockpiled ammo.
As part of the plea agreement, Monper accepted responsibility for additional charges from 2025. The case highlights ongoing concerns about online threats and the FBI's role in monitoring and investigating such activities.
