Several cars at the back of a motorcade carrying Democratic vice presidential nominee Tim Walz crashed while heading from the airport to a campaign stop in Milwaukee on Monday, but Walz was unhurt. Vice President Kamala Harris’ campaign said she spoke with Walz after the crash and that he was not injured. The campaign said the crash involved cars near the rear of the motorcade, not closer to the front. That's where Walz, who is also the governor of Minnesota, was riding.
