Live from DNC Day 4: Kamala Harris, Gretchen Whitmer, and former GOP Rep. Adam Kinzinger

On Thursday, Kamala Harris will give her eagerly-awaited keynote address at the end of the Democratic National Convention.

A slate of Democratic lawmakers, governors, and performers will energize the crowd before Harris delivers her address on night four.

Gretchen Whitmer and Roy Cooper, both former potential running mates for Harris, will be among the speakers at the event, along with The Chicks and Pink who will perform.

In 2021, Kinzinger was one of 10 Republicans in the House who voted to impeach then-President Donald Trump for his role in the January 6 attack on the Capitol. Kinzinger decided not to run for reelection in 2022.

There is speculation and social media buzz about a possible surprise guest for tonight's program, which has been further fueled by Oprah's unexpected appearance on Wednesday.
