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.
The former president took a moment to note the achievements of his signature policy achievement.
"I notice since it became popular, they don't call it 'Obamacare' anymore," he said, prompting laughter.
Obama went on to say Harris will continue to build on that progress.
"Kamala knows we can't stop there, which is why she'll keep working to limit out-of-pocket costs" he said.
Obama commended Harris for her vice presidential selection.
"Let me tell you something. I love this guy," he said of Minnesota Gov. Tim Walz. "Tim is the kind of person who should be in politics. Born in a small town, served his country, taught kids, coached football, took care of his neighbors. He knows who he is and he knows what's important."
He said the Harris-Walz ticket is the embodiment of America's story.
"A story that says we are all created equal, all of us endowed with certain inalienable rights, that everyone deserves a chance, that even when we don't agree with each other, we can find a way to live with each other," he said. "That's Kamala's vision. That's Tim's vision. That's the Democratic Party's vision."
Obama derided Trump's campaign for trying to pit Americans against one another.
"Donald Trump wants us to think that this country is hopelessly divided between us and them, between the real Americans who of course support him and the outsiders who don't," he said. "And he wants you to think that you'll be richer and safer, if you will just give him the power to put those other people back in their place."
"It is one of the oldest tricks in politics from a guy whose act has, let's face it, gotten pretty stale," he continued. "We do not need four more years a bluster and bumbling and chaos. We have seen that movie before. And we all know that the sequel is usually worse."
"America is ready for a new chapter. America is ready for a better story. We are ready for a President Kamala Harris."
Barack Obama at the DNC: 'Trump has not stopped whining'
"Now the torch as been passed," Obama said, turning to Harris' candidacy and her campaign against former President Donald Trump.
"Now it is up to all of us to fight for the America we believe in," he added. "And make no mistake, it will be a fight."
Obama went on to slam Trump as a "78-year-old billionaire who has not stopped whining about his problems since he rose down his golden escalator."
"As we gather here tonight, the people who will decide this election are asking a very simple question: Who will fight for me? Who’s thinking about my future, about my children’s future, about our future together?" he asked. "One thing is for certain, Donald Trump is not losing sleep over that question."
