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.
"After the last two days, aren't you proud to be a Democrat?" he asked the crowd as he began his remarks.
"I'm very grateful to the Republicans and independents that have joined us and I hope they feel better about it now," he said.
He also said he thought his wife, Hillary, gave a "great speech too." Clinton spoke on Monday about how she believed Harris could break the "hardest glass ceiling."
House Minority Leader Hakeem Jeffries got a huge laugh when took a jab at former President Donald Trump, calling him "an old boyfriend who you broke up with, but he just won’t go away."
"He has spent the last four years spinning the block, trying to get back into a relationship with the American people. Bro, we broke up with you for a reason," he said to cheers.

Former President Bill Clinton scrapped a version of his speech after the watching the first night of the convention, several people familiar with the speech told ABC News.
Clinton, who is speaking Wednesday night, revised his speech to make sure the "substance meets the moment" and wanted to strike a more "joyful" tone, after he was struck by the energy of the convention floor, one source said.
A senior adviser to Clinton told ABC News that "it was clear to him that, in the spirit of Mario Coumo, we needed more poetry, not prose."
Cuomo gave the keynote address at the 1984 Democratic convention, saying, "We Democrats must unite so that the entire nation can unite, because surely the Republicans won't bring this country together."
