Walz introduced himself to the country and touted his accomplishments.
The third night of the Democratic National Convention continued the themes of joy and freedom.
A who's who of speakers, including a surprise speech from Oprah Winfrey, headlined the night aimed to showcase vice presidential nominee Minnesota Gov. Tim Walz.
"Coach Walz" brought his energy to the crowd touting his and Vice President Kamala Harris' vision for the future of the country.
Cincinnati Mayor Aftab Pureval has taken the stage. He is Cincinnati's first Asian American mayor and, like Harris, has a parent who immigrated to the U.S. from India.
New York Rep. Tom Suozzi, who flipped a Long Island seat this winter, reiterated his message on the campaign trail about the need to solve the nation's migrant issue.
"To be a nation of immigrants is hard sometimes, too. You have to work for it," he said.
The DNC marks a culmination of decades of Democratic efforts to take back patriotism after years of Republicans owning messaging around "freedom" and the American flag.
The word "freedom" is seemingly on the lips of every attendee and speaker -- and the name of Beyoncé's hit song and now-campaign anthem. Audience chants of "USA!" puncture speakers' remarks as they wave signs saying the same. Camo hats bearing the names of Vice President Kamala Harris and Minnesota Gov. Tim Walz pockmark the crowd. And musician Jason Isbell performed the country hit song "Something More Than Free."

Project 2025, a playbook of controversial policy proposals intended to guide the next conservative administration, has been invoked again during the DNC, this time regarding reproductive rights.
Jessica Mackler, president of EMILYs List, the nation's largest resource for women in politics, called Project 2025 a "blueprint for banning abortion in all 50 states" that will give extremists "the power to monitor your pregnancy."
"Make no mistake -- the threat of Project 2025 is very real," she told the crowd. "But so is our ability to stop it."
