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."

After giving remarks for roughly an hour, Biden was joined by first lady Jill Biden on stage as the song "Higher Love" blared throughout the stadium.

They were soon joined by Vice President Harris and second gentleman Doug Emhoff, both of whom exchanged hugs with Biden.

Other Biden family members also embraced him, including his son Hunter Biden and several of his grandchildren.

At one point, Harris and Biden clasped their hands together and raised them in the air.

All around the stadium, attendees held up vertical "We love Joe" signs echo the shape of the delegation signposts. Former House Speaker Nancy Pelosi was seen on the convention floor with the sign.

Others held up cards that read, "Thank you Joe."

In their box, Vice President Kamala Harris and her running mate Minnesota Gov. Tim Walz sat with their spouses listening to Biden's speech. Walz was emotional throughout much of the president's remarks.

Monday night's DNC programming was scheduled to wrap over an hour ago, by 11 p.m., as Biden continues his keynote speech.

DNC officials addressed the length, blaming the "raucous applause" for going over the time.

"Because of the raucous applause interrupting speaker after speaker, we ultimately skipped elements of our program to ensure we could get to President Biden as quickly as possible so that he could speak directly to the American people," convention officials said in a statement. "We are proud of the electric atmosphere in our convention hall and proud that our convention is showcasing the broad and diverse coalition behind the Harris-Walz ticket throughout the week on and off the stage."
