A man from Butler, Pennsylvania, has admitted to a chilling plot involving threats against the highest levels of American power. Shawn Monper, 32, pleaded guilty to making repeated, violent threats against President Donald Trump, numerous U.S. officials, and agents of U.S. Immigration and Customs Enforcement.
The case unfolded after investigators traced a series of disturbing posts to a YouTube account operating under the name "Mr Satan." The FBI began investigating on April 8, 2025, quickly connecting the online persona to Monper’s residence in Butler, Pennsylvania.
Between January 15th and April 5th, Monper unleashed a torrent of menacing statements. He explicitly declared his intention to “assassinate” President Trump personally, and labeled ICE agents as “terrorist people” deserving of death. He even fantasized about carrying out a mass shooting.
His online rhetoric escalated, framing potential violence as a necessary “American Revolution 2.0.” Monper believed a shift in power was coming, and that those aligned with the former president would be vulnerable and deserving of retribution. He saw himself as part of a majority rising against a perceived minority.
Investigators discovered a disturbing pattern of preparation. Monper had obtained a firearms permit shortly after the initial inauguration, a fact he openly discussed on his YouTube channel. He boasted about acquiring multiple firearms and stockpiling ammunition in response to the political climate.
The threats weren’t limited to broad statements. Monper specifically vowed to treat any armed ICE agent he encountered as a “domestic terrorist” and to immediately open fire. This chilling detail underscored the immediacy and intensity of his violent intentions.
The investigation was a collaborative effort between the FBI and the Butler Township Police Department. Their combined work built a case strong enough to secure Monper’s guilty plea on two counts of threatening to assault and murder U.S. officials and federal law enforcement.
Monper now faces a potential sentence of up to ten years in prison for each count, along with a substantial fine. His sentencing is scheduled for August 12, 2026, leaving the nation to contemplate the gravity of his actions.
This case arrives against a backdrop of previous attempts on the former president’s life. In July 2024, Trump was shot during a campaign rally in Butler, Pennsylvania, and a shooter was killed by the Secret Service.
Just months later, in September 2024, Ryan Routh was arrested while attempting to assassinate the president outside his golf course in West Palm Beach. Routh was subsequently sentenced to life in prison plus seven years, highlighting the very real dangers facing public figures.
