President Biden's closing remarks in his DNC speech:
"I made a lot of mistakes in my career, but I gave my best to you. For 50 years, like many of you, I've given my heart and soul to our nation, and I've been blessed a million times in return with the support of the American people. I remember being too young to be in the Senate because I wasn't 30 yet, and too old to stay as president. But I hope you know how grateful I am to all of you."
