Maryland Gov. Wes Moore discussed how he, Harris and other leaders came together to respond to the March collapse of the Francis Scott Key Bridge.

Moore talked about how several players came together to reopen the port in 11 weeks.

"We are a nation of patriots who serve when the mission is hard and who serve when the destination is uncertain," he said.

At the end of fired-up remarks, Oprah told the crowd: "Let us choose truth, let us choose honor and let us choose joy!"

"Because that's the best of America. But more than anything else, let us choose freedom. Why? Because that's the best of America. We're all Americans. And together, let's all choose Kamala Harris."

Oprah gave tribute to Tessie Prevost Williams, who died earlier this year. Williams was one of four Black girls who helped integrate New Orleans public schools in 1960.

She then tied Williams to Harris, saying Williams "paved the way for another young girl who, nine years later, became part of the second class to integrate the public schools in Berkeley, California.

"Harris famously reflected on her experience as a child being bused to school each day. During a spar with President Biden on the debate stage on busing, Harris told him: "That little girl was me."

Oprah has not mentioned Trump by name, but appeared to reference the former president and his running mate JD Vance.

"America is an ongoing project," she said.

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."
