Welcome to the news hour. Former President Barack Obama is set to headline the second night of the Democratic National Convention here in his political hometown of Chicago.

Mr. Obama will speak in support of Kamala Harris, the party's newly minted standard

bearer, delivering what a campaign official says will be a forceful affirmation that

Harris is the right leader for the moment.

The former president's appearance comes one night after the sitting president,

Joe Biden, delivered a fiery speech in defense of his decision to step aside

and in support of Harris.

Laura Barone Lopez has been watching it all closely and she's on the convention

floor now, Laura.

Jeff and Omni, the first night of the DNC began to tell the story of

Kamala Harris. But it was also a moment for the party to mark those who came

before her and created this pathway for her to ultimately rise and to chart a new pathway for

Democrats. I would like to introduce my father, your 46 president of the United States, Joe Biden.

President Biden took the stage with an embrace from his daughter Ashley.

Wiping a tear from his eye as delegates and attendees did the same. Thank you, thank you, thank you.

Greeted by a sea of signs that read We Heart Joe and Chants of his name.

The crowd gave him a standing ovation that lasted nearly five minutes.

It was a scene that could have been his own party nomination

on the final night of the convention.

But this was more of a goodbye.

Let me know in my heart when my days are through.

America, I gave my best to you but I gave my best to you.
