Records show Monper obtained a concealed carry permit in January 2025. He faces a sentencing hearing on August 12 and could receive up to 10 years per count, fines up to $250,000, or both, the DOJ noted.
Monper lived in Butler, Pennsylvania, which was the site of a July 2024 rally attack in which a gunman fired into the crowd; that earlier incident resulted in one attendee's death and the gunman was neutralized by protective agents. Federal officials have emphasized reducing violent rhetoric after that event.
