ROCHESTER, Pa. (AP) — Democratic presidential nominee Kamala Harris and running mate Tim Walz gave pep talks to campaign volunteers and a high school football team Sunday. Their bus tour in a corner of Pennsylvania is serving as a modest, small-town version of the grand rally she’s expected to have at the Democratic nominating convention in Chicago this week. Vice President Harris and Walz, the governor of Minnesota, visited volunteers at a campaign office not far from Pittsburgh before continuing on to a firehouse and a high school in another town. The tour, in a bright blue bus bearing the candidates’ names and the phrase “A new way forward,” also included pilgrimages to a convenience store and a restaurant known for its towering sandwiches.
