Several cars were hit when live ordnance was detonated over Interstate 5 in San Diego County, despite Governor Gavin Newsom's prior warnings about the dangers.
Although no one was injured, the blast caused shrapnel to fall, damaging several vehicles, including a motorcycle from Vance's protection detail.
Newsom criticized the federal government on social media, saying that President Donald Trump and Vance “put lives at risk to put on a show.”
The California Highway Patrol also deemed the military exercise “unusual” and “concerning,” while Vance's communications director dismissed Newsom's safety concerns as overreactions to a routine exercise.
