PHILADELPHIA—Minnesota Gov. Tim Walz debuted as Vice President Kamala Harris’s running mate at a campaign rally here on Tuesday evening, just hours after being announced as the nominee.
Walz, a former high school football coach and 24-year veteran of the Army National Guard, lived up to his reputation at the event as a plainspoken Midwesterner. He salted his remarks with homespun expressions and presented his left-of-center policy positions with a personal touch.
