A motorcycle that is part of Vice President JD Vance's security detail and a California Highway Patrol car were hit with shrapnel on Saturday after a 155-millimeter shell exploded over Interstate 5 during a live-fire demonstration for the Marines' 250th anniversary on Saturday, according to a new report. Officials told The New York Times that the explosion was a "mishap" and that no officers were injured. California Gov. Gavin Newsom had ordered the freeway to be closed ahead of the celebration after reports emerged that the Trump administration was planning to fire live ordnance at the event.
