Minnesota Gov. Tim Walz's motorcade was involved in a multi-car crash on Monday while en route to a Labor Day event in Milwaukee, though Walz was uninjured. The collision occurred shortly before 1 p.m. ET, affecting vehicles at the back of the motorcade, with a member of the press staff sustaining a possible broken arm and others reporting minor injuries. Following the incident, President Biden and Vice President Kamala Harris both contacted Walz to check on his well-being. The cause of the crash remains unclear, but initial reports suggest a stopped vehicle may have contributed to the incident. The motorcade was delayed for about an hour while emergency responders attended to the injured, and the press eventually transferred to new vehicles to continue to the event. This incident marks the second motorcade crash involving a candidate this campaign season, following an earlier incident involving Florida Gov. Ron DeSantis.
