A California Highway Patrol (CHP) vehicle sustained damage from metal shrapnel originating from an explosive artillery shell during a Marine Corps live-fire training exercise. This unusual event took place on Saturday near a prominent highway, as reported by the CHP. The incident unfolded close to Interstate 5 in San Diego County, adjacent to Camp Pendleton.

Interestingly, the occurrence coincided with a celebratory event at the base, marking the Marines’ 250th Anniversary. Notable attendees included Vice President Vance and Defense Secretary Pete Hegseth, both present to honor this significant milestone on November 10.

Fortunately, no injuries were reported following the incident. The California Highway Patrol promptly communicated with the Marines at the scene, resulting in the cancellation of additional firings. An internal report on the event has been filed, urging a thorough review of the “planning, communication, and coordination between federal, state, and local government” for such demonstrations.

Reacting to the mishap, CHP Border Division Chief Tony Coronado expressed his concerns, describing the incident as “unusual and concerning.” He emphasized that it is “highly uncommon for any live-fire or explosive training activity to occur over an active freeway.”

Coronado, himself a Marine, underscored his respect for the military while reaffirming his primary duty to ensure the safety of California’s residents and the officers who protect them. His statement underscores the importance of balancing military training needs with public safety considerations.

The Hill has reached out to the Marines for comment. 

Prior to the demonstration, Democratic California Gov. Gavin Newsom temporarily closed the highway due to safety concerns. In a statement before the event, Newsom said the administration was “using our military to intimidate people [they] disagree with,” adding that he closed the highway at the recommendation of CHP traffic safety experts.

On the social platform X on Saturday, the White House’s rapid response team said the Marines “repeatedly said there are no public safety concerns with today’s exercises.”

Later in the afternoon, after the incident, Newsom’s press office said the White House “misled Californians about the live munitions” being shot over the highway. 

“Without a doubt an apology is owed — to not just Californians, but all Americans,” his office added.
