DNC 2024 Day 3: Tim Walz tells Democrats to 'leave it on the field'

Former President Bill Clinton scrapped a version of his speech after the watching the first night of the convention, several people familiar with the speech told ABC News.

Clinton, who is speaking Wednesday night, revised his speech to make sure the "substance meets the moment" and wanted to strike a more "joyful" tone, after he was struck by the energy of the convention floor, one source said.

A senior adviser to Clinton told ABC News that "it was clear to him that, in the spirit of Mario Coumo, we needed more poetry, not prose."

Cuomo gave the keynote address at the 1984 Democratic convention, saying, "We Democrats must unite so that the entire nation can unite, because surely the Republicans won't bring this country together."

Actress Mindy Kaling is tonight's celebrity host.

In 2019, she and Harris went viral for a video in which they prepared masala dosa, a South Indian dish.

In her introduction, Kaling referred to herself as "the woman who courageously outed Kamala Harris as Indian in an Instagram cooking video."

Democrats have already brought out multiple celebrities Wednesday, including musical legend Stevie Wonder and comedian Kenan Thompson. The crowd roared each tome in surprise.

John Legend will also perform later.

Both parties have used celebrities, including wrestler Hulk Hogan at the Republican National Convention.

"This year I prayed very hard for peace to come to our worlds nations, but also to each one of our hearts." he said in remarks before his performance.

"Even though our hearts have been beaten and broken beyond prayer, I know the important action and now is the time to understand where we are and what it will take to win. Win the broken hearts. Win the disenchanted, when the angry spirit. Now is the time," he said.
