DNC 2024 Day 1 live updates: Emotional Joe Biden casts election as choice to 'save democracy'
"I hope you know how grateful I am to all of you," Biden said.
Democrats kicked off their convention Monday with a who's who of guests who all touted Vice President Kamala Harris' run for the White House.
Several topics came up during the night including the future of reproductive rights and Project 2025.
Harris made a surprise appearance after several Democratic VIPS took the stage, including Rep. Alexandria Ocasio-Cortez.
The main stars of the night were some of the Democrats' longstanding figures including Secretary of State Hillary Clinton.
But the main spotlight came as President Joe Biden spoke to the cheering crowd, reflecting on his four years as president and his decision to "pass the torch" to Harris.

'America, America, I gave my best to you': Biden
Biden closed his speech by citing a verse from the song "American Anthem," which he says has meant a lot to him and his family.
He said he would spare the crowd his singing so just quoted the verse: "America, America, I gave my best to you."
"I gave my best to you for 50 years," Biden said. "I hope you know how grateful I am to all of you."
He ended his speech saying he's more optimistic about the future than he was when he was first elected to the Senate at the age of 29.
"Folks, we just have to remember who we are," he said. "We're the United States of America. And there's nothing we cannot do when we do it together."
