Obama praised President Biden and offered support for Harris.
Vice President Kamala Harris officially became the official Democratic presidential nominee during the second night of the Democratic National Convention.
The night included a lively and upbeat roll call vote of delegates that featured a DJ, some celebrities and energetic speeches. Also, Harris, who campaigned in Milwaukee, thanked the crowd in a live-streamed message.
Second gentleman Doug Emoff talked about his long relationship with Harris and touted her vision for the country.
But the night's biggest headline was the return of former President Barack Obama and first lady Michelle Obama to the DNC stage. Both stressed what's at stake in this election and pushed Americans to come together to bring the country to a better future.
Rapper Common and gospel musician Jonathan McReynolds took to the stage.
Common changed up the lyrics to his song "Fortunate" for the DNC, rapping, "Be fortunate, y'all, for Kamala Harris."
Jason Carter, the grandson of former President Jimmy Carter, was the first speaker of the night.
"Kamala Harris carries my grandfather's legacy," he said. "She knows what is right and she fights for it. She understands that leadership is about service, not selfishness."
Jimmy Carter, who is in hospice care and is nearing his 100th birthday in October, told his family he wants to make it to vote for Harris in November, Jason Carter said.
"Papa is holding on. He is hopeful, and though his body may be weak tonight, his spirit is as strong as ever," Jason Carter said.

Those remembered included former first lady Rosalynn Carter and California Sen. Dianne Feinstein.
The second night of the DNC is officially underway in Chicago.
Tonight's theme is "A bold vision for America's future" and will feature a keynote address by former President Barack Obama.
The convention will also hold a ceremonial roll call for Harris, who became the official Democratic presidential nominee following a virtual roll call earlier this month.
