Full Report
Arrest and Charges
Vandenberg was apprehended after purchasing fireworks and alarming store employees with his intentions to target law enforcement at the upcoming protests. His inquiries about the fireworks’ gunpowder content and their potential to inflict harm raised suspicions and led to his arrest.
During the arrest in Arizona, authorities discovered clothing featuring antisemitic and extremist symbols, including a t-shirt depicting the Al-Qaeda flag. A review of his phone revealed messages manifesting resentment toward the U.S. government, particularly directed at President Donald Trump, based on his belief that the government was under the control of Israel and Jews.
Court Statements
Acting U.S. Attorney Ryan Ellison emphasized the importance of peaceful expression of beliefs while condemning any use of explosives to intimidate or terrorize others. He stated that Vandenberg’s actions represented an egregious attempt to employ violence as a means of political expression, warranting severe federal repercussions.
Following the conviction, the court mandated that Vandenberg remain in custody until sentencing, which has yet to be scheduled.
