Television star Oprah Winfrey got one of the biggest ovations of the night as the DNC crowd shot to its feet when she walked on stage.

"It requires commitment. It requires being open to the hard work and the hard work of democracy, and every now and then, it requires standing up to life's bullies."

She then brought up Vance's "childless cat lady" comments to cheers.

"Despite what some would have you think we are not so different from our neighbors," she said. "When a house is on fire, we don't ask about a homeowner's race or religion. We don't wonder who their partner is or how they voted. No, we just try to do the best we can to save them. And if the place happens to belong to a childless cat lady, well, we try to get that cat out too."

"What we're going to do is elect Kamala Harris as the next president of the United States," she said after taking the stage.

"What we're going to do is elect Kamala Harris as the next president of the United States," she said after taking the stage.

The first time Oprah put her legacy brand behind a political candidate was Barack Obama in 2008.

"That was some epic fire," she said of the Obamas speeches last night, taking inspiration from Michelle Obama's call on the crowd to "do something!"

Television star Oprah Winfrey got one of the biggest ovations of the night as the crowd shot to its feet when she walked on stage.

Amanda Gorman, who gained national fame after reciting her poem "The Hill We Climb" at the Biden-Harris inauguration in 2021, read a new poem at the DNC that stressed unity.

She said everyone is there because "we believe in the American dream" but that is being tested.

"It falls to us to ensure that we do not fall, for a people that cannot stand together, cannot stand at all," she said.

"We are one family, regardless of religion, class, or color, for what defines a patriot is not just our love of liberty, but our love for one another," she continued.

"This is loud in our country's call because while we all love freedom, it is love that frees us all," she said to applause.

She ended her poem with, "Let us not just believe in the American dream, let us be worthy of it."
