Core Event: Foiled Explosives Plot
Gregory Vandenberg, a 49-year-old former U.S. Navy SEAL, was found guilty after a five-day federal trial of transporting explosives with intent to kill, injure or intimidate law-enforcement officers and of attempting to transport prohibited fireworks into California. Jurors deliberated for roughly three hours before returning the verdict. While driving from El Paso, Texas, to San Diego ahead of the scheduled June 14, 2025 “No Kings” demonstrations, Vandenberg stopped at a travel center near Lordsburg, New Mexico. There he purchased six mortar-style fireworks and 72 M-150 firecrackers, telling the clerk he planned to throw the devices at police, inquiring about gunpowder content and whether taping mortars together would increase their force. He also urged the clerk to attend the protests and distribute fireworks to others. The clerk recorded Vandenberg’s license plate and alerted authorities, leading federal agents to arrest him the next morning while he slept inside his vehicle at Davis-Monthan Air Force Base in Tucson, Arizona.
Background & Context
The plot was linked to the “No Kings” protest, a movement that attracted extremist participants. A search of Vandenberg’s vehicle uncovered clothing bearing an Al-Qaeda flag, a shirt calling for the destruction of Judea, a Black Sun symbol associated with neo-Nazi ideology, and a cellphone home screen displaying a Taliban flag. Prosecutors said messages on the phone reflected Vandenberg’s belief that the U.S. government, including President Donald Trump, was controlled by Israel and Jewish people, establishing a motive for targeting police.
Data & Statistics
- Six mortar-style fireworks and 72 M-150 firecrackers purchased
- Five-day trial, three-hour jury deliberation
- 16-month federal prison sentence, followed by one year of supervised release
- Vandenberg’s age: 49
Official Statements & Responses
Acting U.S. Attorney Ryan Ellison emphasized that while individuals may hold and express beliefs peacefully, using explosives to threaten or terrorize is unlawful. He noted that Vandenberg intended to turn explosives into a tool of intimidation and that the verdict signals federal commitment to punish attempts to substitute violence for speech.
Impact & Outlook
Vandenberg remains in custody and will serve his sentence before entering supervised release. The case highlights law-enforcement vigilance against extremist plots targeting public demonstrations and reinforces the message that violent intimidation will be met with federal consequences.
