Vice President Kamala Harris officially became the official Democratic presidential nominee during the second night of the Democratic National Convention.

The night included a lively and upbeat roll call vote of delegates that featured a DJ, some celebrities and energetic speeches. Also, Harris, who campaigned in Milwaukee, thanked the crowd in a live-streamed message.

Second gentleman Doug Emoff talked about his long relationship with Harris and touted her vision for the country.

But the night's biggest headline was the return of former President Barack Obama and first lady Michelle Obama to the DNC stage. Both stressed what's at stake in this election and pushed Americans to come together to bring the country to a better future.

DNC will start half an hour earlier on Tuesday

The DNC will start its programming half an hour earlier than originally planned on Tuesday after Monday's program had a delayed start that pushed President Joe Biden's speech past prime time and cut short his farewell.

"We had so much energy and enthusiasm for our president, our ticket, from our speakers and the audience reaction that I recognize that did put us a little bit behind schedule, but we are working with -- we made some real-time adjustments last night to ensure we could get to what the delegates and the viewers really came for, which, of course, is President Biden," Alex Hornbrook, the executive director of the convention, told reporters this morning.

"And we're working with our speakers and making some other adjustments for this evening, including beginning at 5:30 to make sure that we stay on track for that tonight," he added.

Obamas to make prime-time speeches

The attention on Day 2 of the Democrats’ gathering shifts from celebrating President Joe Biden to prime-time speeches from former President Barack Obama and former first lady Michelle Obama. They'll help pass the party torch to Kamala Harris.

The convention will also hold a ceremonial roll call to nominate Harris, which follows the party's virtual process doing so earlier this month. Harris officially had the vast majority of delegate votes needed to secure her nomination when that process ended on Aug. 6.

It’s expected that California Gov. Gavin Newsom and Harris’ home state delegation will cast the vote putting her over the top.
