In an X post Thursday night, President Joe Biden said he and the first lady just talked to Harris ahead her speech at the convention coming up.

He added that they "can’t wait to watch her accept this historic nomination."

"Kamala and Tim will inspire a generation and lead us into the future," Biden said in the post.

Marchers took to the street before sundown on the final day of the DNC. They stretched for more than a mile and took nearly three hours to reach its final destination in Union Park, four blocks west of the stadium.

Hatem Abudayyeh, spokesperson for the coalition, said nearly 8,000 people were in the streets marching. Their goal all week was to raise awareness of the plight of Palestinians, which he said was a success, especially when President Joe Biden mentioned the protestors in his speech Tuesday.

"It means people know we are here, and they are talking about us," he said.

As marchers slowly moved through a residential street, just two blocks from the stadium, they banged drums, chanted ("just like 1968/nothing here to celebrate") and taunted Chicago police officers who lined both sides of the street with bicycles.

A skirmish briefly forced the march to pause when several people surrounded Chris Eston, 21, of Peoria, who carried an American flag. After a block of pushing and shoving with the coalition protestors, Eston eventually was ejected from the street by police officers.

"They called my fascist," he said of the marchers. "I told them in a true fascist country, protests don't exist. If they'd do this in Iran, they'd get shot."

Several members of Harris' family, including stepdaughter Ella Emhoff and niece Meena Harris, were up on stage addressing the DNC. Her sister, Maya Harris, is also slated to speak later tonight.

Here's what to know about her family.

Kerry Washington took the stage to kick off prime-time coverage.

She began by criticizing any naysayers about a celebrity being at the convention and noted that this was not her moment, but every American's.

"You are the messengers. You are the fixers. Dare I say it? You are the Olivia Popes," she said referring to her character on the hit ABC show "Scandal." "You are the superheroes saving this democracy."

Washington ended her speech with a reunion with her "Scandal" co-star Tony Goldwyn, who came out to take a selfie with the roaring crowd.
