Barack and Michelle Obama Rally for Kamala Harris at DNC 2024

Barack and Michelle Obama urged Democrats to unite behind Vice President Kamala Harris on the second night of the party's convention in Chicago on Tuesday, challenging the assembled delegates and voters at home to harness the enthusiasm surrounding Harris' candidacy to defeat Donald Trump in November.

"We do not need four more years of bluster and bumbling and chaos. We have seen that movie before, and we all know that the sequel is usually worse," Barack Obama said in his 34-minute address. "America's ready for a new chapter. America's ready for a better story. We are ready for a President Kamala Harris."

The 44th president took on Trump directly, calling him "a 78-year-old billionaire who has not stopped whining about his problems since he rode down that golden escalator nine years ago." But Obama also said Democrats cannot be complacent and must lay out a vision for the future.

"Our job is to convince people that democracy can actually deliver. And in doing that, we can't just point to what we've already accomplished. We can't just rely on the ideas of the past. We need to chart a new way forward to meet the challenges of today. And Kamala understands this," Obama said, highlighting Democratic policies on housing, health care, the economy, immigration and more.

Michelle Obama struck a similar tone as her husband, noting that "hope is making a comeback" with Harris' candidacy but imploring Democrats to get to work.

"It's up to us to remember what Kamala's mother told her: Don't just sit around and complain — do something," she said. "So if they lie about her, and they will, we've got to do something. If we see a bad poll, and we will, we've got to put down that phone and do something."
