Domestic Terrorism and Political Violence

Shawn Monper, a man from Butler County, Pennsylvania, has pleaded guilty after an FBI investigation found he posted online threats to assassinate former President Donald Trump and to kill U.S. Immigration and Customs Enforcement (ICE) agents. The case concluded with Monper admitting the online statements and accepting responsibility in federal court; law enforcement officials say the investigation traced the threats to his online activity and determined they constituted credible criminal conduct rather than protected speech.
