Harris acknowledged Tuesday that “of course” it is possible that Trump could declare victory before all the votes are counted next month.

"This is a person, Donald Trump, who tried to undo a free and fair election, who still denies the will of the people, who incited a violent mob to attack the United States Capitol and 140 law enforcement officers were attacked, some who were killed," Harris told NBC's Hallie Jackson in a clip of their interview that was released Tuesday afternoon.

Harris said that she and her team "will deal with election night and the days after as they come, and we have the resources and the expertise and the focus" on that scenario.

The Georgia Supreme Court on Tuesday denied an effort from the Republican National Committee to reinstate a series of election rules, including requiring ballots be counted by hand, after they previously were blocked by a lower judge.

The state's high court ruling was unanimous, according to the order.

The lower court judge previously ruled that seven election rules passed by the state's Republican-led Election Board were "unlawful and void." The RNC then appealed, with RNC chairman Michael Whaley in statement saying the judge "exemplified the very worst of judicial activism."

The order from the Georgia Supreme Court on Tuesday said the appeal "will proceed in the ordinary court" once it is docketed.

Over 21 million Americans have voted early as of Tuesday afternoon, according to data from Election Lab at the University of Florida.

Roughly 7.8 million votes have come in through early in-person methods while the remaining votes -- over 13 million -- have been cast through mail ballots, the data showed.

There is a large showing of early votes in the swing state of Georgia which has seen record early vote turnout since early in-person voting began last week.

As of Tuesday afternoon, more than 1.84 million Georgians, roughly one in four registered voters, have cast their ballot, with over 1.74 million votes cast at early voting polling places across the state according to Georgia's Secretary of State office.

Trump is set to tape an interview for the popular "Joe Rogan Experience" podcast Friday at Rogan’s Austin, Texas, studio, multiple sources told ABC News.

Rogan’s podcast garners a vast amount of viewership each week and ranks as one of the most-listened-to podcast on Spotify.

The interview comes as Trump has been engaging in more long-format media appearances and podcasts and works to appeal to young male voters, a key group of Rogan listeners.

Earlier this cycle, Rogan and Trump got into a back-and-forth spat on social media after Rogan expressed his support for then-candidate Robert F. Kennedy Jr. during on an episode over the summer.

“He's the only one who makes sense to me," Rogan said of Kennedy in an August episode.

"He doesn't attack people. He attacks actions and ideas, but he's much more reasonable and intelligent."

In response, Trump posted on his social media platform that “it will be interesting to see how loudly Joe Rogan gets BOOED the next time he enters the UFC Ring??? MAGA2024.”

Trump said the Biden-Harris administration's immigration and border policies had made the U.S. a "dumping ground" for other countries during a rally at Tempe, Arizona, on Thursday.

"We're like a garbage can for the world," Trump said. "And every time I come up and talk about what they've done to our country, I get angrier and angrier. [It's the] first time I've ever said 'garbage can.' But you know what? It's a very accurate description."

Trump also said he watched Harris' town hall on CNN Wednesday night, an event Trump declined to attend, and said she was "pathetic."

The former president also criticized President Joe Biden for a gaffe he made telling voters that Trump should be "locked up" before adding "politically."

"He's such a stupid guy. Such a stupid fool," Trump said.
