A Pennsylvania man’s months-long online campaign threatening to assassinate President Trump and federal agents has ended in a guilty plea, exposing the dark reality of violent extremism festering on social media platforms while raising serious questions about how such explicit threats went undetected for months.
Story Snapshot
- Shawn Monper, 32, pleaded guilty to threatening to kill President Trump, ICE agents, and other officials in YouTube posts under the username “Mr Satan”
- Threats included vows to personally assassinate Trump and calls for “American Revolution 2.0” while stockpiling weapons and body armor
- The Butler, Pennsylvania resident posted violent rants for nearly three months before the FBI was notified and made an arrest
- Monper faces up to 20 years in federal prison and $500,000 in fines at his August 2026 sentencing
Months of Unchecked Violent Threats
Between January 15 and April 5, 2025, Monper posted a series of increasingly violent threats on YouTube targeting President Trump, federal agency heads, ICE agents, Elon Musk, teachers, and Representative Marjorie Taylor Greene. His posts included explicit promises to “assassinate” Trump personally and calls to “start killing” federal officials he labeled as “terrorist people.” The threats came shortly after Trump’s second inauguration, specifically targeting policies related to immigration enforcement. Monper also referenced plans for a mass shooting and proclaimed “American Revolution 2.0,” detailing his acquisition of firearms, ammunition, body armor, and a firearms permit.
FBI Response and Arrest
The FBI received notification of Monper’s threatening YouTube account on April 8, 2025, nearly three months after the threats began. Agents quickly traced the “Mr Satan” account to Monper’s residence in Butler, Pennsylvania, collaborating with the Butler Township Police Department. Law enforcement arrested Monper the following day, April 9, 2025. FBI testimony confirmed the credibility and seriousness of the threats, noting they demonstrated clear intent to impede or retaliate against federal officials performing their duties. The swift arrest following notification raises troubling questions about why YouTube’s content moderation systems failed to flag such explicit death threats earlier.
Butler’s Troubling Connection to Violence
The case carries added significance given Butler’s connection to the July 13, 2024 assassination attempt against Trump during a campaign rally, where the former president was shot in the ear by an assailant later killed by Secret Service agents. Monper’s threats emerged in the aftermath of that attack, demonstrating that violent extremism targeting the president persisted in the very community that witnessed an actual assassination attempt. His YouTube rants framed MAGA supporters as a “minority” while calling for armed violence against Trump administration officials, reflecting the dangerous polarization following Trump’s return to the White House.
Legal Consequences and Broader Implications
Monper entered his guilty plea in federal court on a Monday prior to April 14, 2026, admitting to two counts of threatening to assault and murder U.S. officials. U.S. District Judge W. Scott Hardy will sentence Monper on August 12, 2026, with the defendant facing a maximum of 10 years imprisonment on each count and fines up to $250,000 per count. The Department of Justice prosecution sends a clear message about the consequences of online threats against federal officials. However, the case highlights systemic failures in social media monitoring that allowed violent extremism to flourish unchecked for months, raising concerns about whether tech platforms are adequately protecting elected officials and federal agents from credible threats during this period of intense political division.
