Former U.S. Navy SEAL Convicted of Transporting Explosives to Throw at Law Enforcement at California Protests

Evidence Reflected Violent Extremist Beliefs and Deep Hostility Toward the U.S. Government ALBUQUERQUE – After a five-day jury trial and approximately three hours of deliberation, a federal jury convicted Gregory Vandenberg, a former U.S. Navy SEAL, of intending to use explosives against law enforcement officers at the June 14, 2025, “No Kings Day” protests in California. According to court records and evidence presented at trial, on Thursday, June 12, 2025, Gregory Vandenberg, 49, was traveling from El Paso, Texas, to San Diego, California, to attend the “No Kings Day” protests, which were scheduled for Saturday, June 14, 2025. While in New Mexico, Vandenberg visited a travel center off Interstate 10 near Lordsburg and purchased six large mortar fireworks, which are designed to shoot high into the air and explode, and 72 M-150 firecrackers, which are designed to sound like gunfire. During this visit, he told the store clerk that he intended to throw fireworks at police officers at the upcoming protests. He asked detailed questions about the amount of gunpowder in the fireworks, their explosive impact, and their ability to harm others. He also discussed taping multiple fireworks together to increase their explosive impact. Vandenberg emphasized that he was not interested in the color or display of the fireworks—only in their ability to cause explosions and harm law enforcement. Vandenberg, who has no stable employment and lives primarily out of his car, also made several statements demonstrating his knowledge of explosives and past special forces experience. He encouraged the clerk to join him at the protests and repeatedly expressed a desire to throw fireworks at law enforcement officials at the protests in California. He also discussed handing out fireworks to others at the event and noted that he would not get hurt because he knew what he was doing. When purchasing the fireworks, he falsely told the cashier that he was not from this country when she asked for his I.D., and he asked if the store was going to track him. Employees, alarmed by his comments, recorded his license plate and contacted law enforcement. Federal agents tracked Vandenberg to Tucson, Arizona, and arrested him the following morning while he was sleeping in his car at Davis-Monthan Air Force Base. Vandenberg initially claimed to be traveling for work and later falsely stated he was visiting friends in Phoenix that weekend, though he was unemployed at the time. A search of his vehicle revealed the purchased fireworks, along with clothing displaying antisemitic, anti-Israel, and extremist symbols—including a t-shirt with an image of the Al-Qaeda flag and a t-shirt calling for the destruction of Judea. FBI agents also discovered that the home screen on Vandenberg’s phone consisted of an image of the Taliban flag. It was further discovered that Vandenberg wore a t-shirt into the store that stated “AMALEK” in large letters on the front—a t-shirt that Vandenberg had specially made and that he stated meant the “destroyer of Jews.” A review of his phone showed violent and extremist content, including antisemitic, anti-Israel and anti-U.S. materials, as well as messages discussing the upcoming protests. A review of his phone also showed messages suggesting Vandenberg was upset with the U.S. government, including President Trump, because he viewed the U.S. government as being controlled by Israel and the Jews. “People in this country are free to hold their own beliefs and to express them peacefully,” said Acting U.S. Attorney Ryan Ellison. “What they are not free to do is use explosives to threaten or terrorize others. Vandenberg intended to turn explosives into a tool of intimidation, and this verdict sends the message that attempts to substitute violence for expressing one’s opinion has no place in our communities and will be met with federal consequences.” Vandenberg was convicted of transportation of explosives with intent to kill, injure or intimidate and attempted transportation of prohibited fireworks into California. Following the verdict, the Court ordered that Vandenberg remain in custody pending sentencing, which has not been scheduled. At sentencing, Vandenberg faces 10 years in prison.
