San Diego, California – Governor Gavin Newsom has criticized the White House for what he described as a “reckless” military display that occurred during Vice President JD Vance’s visit to the state on Saturday, October 18, 2025. The event, held at Camp Pendleton to mark the 250th anniversary of the Marine Corps, became controversial when an artillery shell accidentally detonated, damaging a California Highway Patrol (CHP) vehicle and a motorcycle that was part of the Vice President’s protective detail.
Newsom had previously expressed concerns about the military display, warning the administration that it could be “dangerous” due to insufficient coordination between federal, state, and local agencies. In a post on social media platform X, formerly known as Twitter, he highlighted the risks posed to California residents, particularly emphasizing the danger of live rounds being fired over a busy highway. As a result of the incident, I-5 freeway, a critical transportation route serving approximately 80,000 travelers daily and facilitating $94 million in freight, was shut down, and afternoon rail service running parallel to the highway was canceled.
The Marine Corps, while stating they did not request the closure of the freeway, acknowledged the public’s patience during what they characterized as essential training exercises. The demonstration included live artillery fire from M777 Howitzers and maneuvers by amphibious vehicles, both of which are integral to military operations. CHP Border Division Chief Tony Coronado reiterated that conducting live-fire exercises over an active freeway is highly uncommon and stressed that maintaining public safety remains a top priority.
Despite no injuries reported from the incident, the CHP has launched an after-action review to evaluate the communication and planning involved in such military events near public roadways. The circumstances surrounding the live-fire event have raised questions about the appropriateness of such exercises within civilian areas, especially considering the historic context of military displays in public settings.
During the event, Vice President Vance did not address the ongoing “No Kings” protests, which aimed to manifest opposition to perceived overreach by the Trump administration. Instead, he used the platform to critique Democrats for pushing diversity initiatives in military ranks. Vance’s spokesperson defended the training exercise, asserting that it is vital for ensuring the Armed Forces remain capable and prepared.
Transportation officials justified the closure of I-5 by noting safety risks associated with artillery fire and the potential for driver distraction. The incident has sparked a broader dialogue regarding the implications of military exercises occurring near populated areas, coinciding with nationwide protests against President Trump’s administration and criticism of military use for intimidation purposes.
Governor Newsom characterized the event as exhibiting “chaos and confusion,” contrasting it with true military strength. He condemned the administration for prioritizing personal interests over public safety and called for a more respectful approach when celebrating military milestones.
This incident highlights ongoing tensions surrounding military displays, public safety, and the coordination needed when such events occur in proximity to civilian populations. As discussions continue, officials are likely to re-evaluate the policies and procedures governing military training activities within urban environments to ensure the safety of residents and maintain public trust.
