Vice President Kamala Harris and Gov. Tim Walz stopped by Liberty County High School in Georgia as part of their bus tour and were greeted by the school’s principal and superintendent and met with the school marching band during rehearsal.
Harris and Walz delivered brief remarks to band members, football players and faculty. After welcoming the class to the "role model club," Harris told the class that as "leaders" the nation is "counting" on them.
"You are showing what hard work can achieve, what discipline, what teamwork. And that's the stuff of greatness," she said.
She continued with a music metaphor that encouraged them to keep up their hard work.
"I will tell you I was in band when I was your age," she said. "And all that you all are doing, it requires a whole lot of rehearsal, a whole lot of practice, long hours, right? Sometimes you hit the note, sometimes you don't, right? All that practice makes for beautiful music."

A spokesman for the Harris-Walz campaign defended Wednesday the decision to make the vice president's first televised interview as the Democratic presidential nominee a joint interview with her running mate Gov. Tim Walz.
Ian Sams responded on X to a post by journalist Mark Knoller who questioned if CNN should have "insisted on a one-on-one interview," by saying that "The joint ticket interview is an election year summer tradition going back 20 years."
"Kerry/Edwards, Obama/Biden, Romney/Ryan, Trump/Pence, Clinton/Kaine, Biden/Harris all did them. Almost always right around the conventions. Harris/Walz join this rich tradition on CNN tomorrow," he said.

Vance told reporters he’s preparing for the October vice presidential debate by talking to people on the campaign trail, contending he doesn’t need other preparation against Minnesota Gov. Tim Walz.
“Look, the way I'm doing debate prep is by spending time with these fine people. This is how I do debate prep is to get out there. You get out there, you talk to people, you talk about the issues that matter,” Vance said.
“We don't need to prepare for a debate with Tim Walz. We need to get out there and talk. We need to get out there. Look, we need to get out there and talk to the American people. That's the biggest way that we're going to prepare for that debate on October the first,” he added.
