Before the Obamas take the stage Tuesday, the DNC will feature speeches from second gentlemen Doug Emhoff, Senate Majority Leader Chuck Schumer and Sen. Bernie Sanders, according to the convention's schedule.

Maryland Senate candidate Angela Alsobrooks will deliver the keynote remarks.

Remarks are also expected from former Trump White House press secretary Stephanie Grisham, as well as Jason Carter and Jack Schlossberg, the grandsons of former Presidents Jimmy Carter and John F. Kennedy, respectively.

Rep. Maxwell Frost, the youngest member of Congress, spoke with ABC News Live anchor Kyra Phillips about the enthusiasm Gen Z has for Kamala Harris.

"Young people are excited about Kamala Harris and I think it's for many different reasons," he said. "No. 1, it's her authenticity. She's been going viral on TikTok, online, Twitter and a lot of it has to do with her as a human, her as a person, the things she loves, who she is, and the things she says."

Frost added that young people like Harris because "they hear her message, and then they see themselves represented in her and what she's fighting for and all the amazing people that we have here today."

Protesters interrupt Tim Walz's women's caucus remarks

Minnesota Gov. Tim Walz's remarks Tuesday to the women's caucus at the DNC were interrupted by pro-Palestinian protesters.

Minnesota Gov. Tim Walz's remarks Tuesday to the women's caucus at the DNC were interrupted by pro-Palestinian protesters.

Walz was recognizing the role women had in aiding him as governor, and was praising former Secretary of State Hillary Clinton and Vice President Kamala Harris before demonstrators started chanting, "Stop killing women in Gaza! Stop killing women in Gaza!"

They unfurled banners in the middle of the room as the audience tried to drown out their protest.

Walz briefly paused his remarks and looked at the protesters before continuing his speech, without acknowledging them.

The protesters were escorted out of the ballroom where they continued their calls for a cease-fire in Gaza and for the end of arms transfers to Israel.

A delegate, who only identified herself as Michelle and a New York delegate, fiercely countered the protesters, accusing them of helping Donald Trump by protesting.
