Live election updates: 80 million have voted early as Trump, Harris sprint to finish

The Cybersecurity and Infrastructure Security Agency continues to see threats towards election officials a day before Election Day, according to a top official for CISA, the cyber arm of the Department of Homeland Security.

In a call to reporters Monday, Cait Conley, who is in charge of CISA's election security portfolio, called these threats "fundamentally un-American."

CISA Director Jen Easterly said most local elections officials are in touch with law enforcement.

"We've not seen specific reporting about violence at polling places, so I certainly don't want voters to feel at all intimidated about going to voting locations," Easterly said, saying it should "really be a day of celebration."

Easterly said they "expect" disruptions throughout Election Day, and they are prepared for it. Foreign adversaries -- particularly Russia, China and Iran -- are looking to "undermine American confidence and the legitimacy of our elections and to stoke partisan discord," she said.

Before announcing the winners of Elon Musk's $1 million giveaway, America PAC employees conducted background checks on them, vetted their social media and had them sign non-disclosure agreements, Elon Musk's political adviser Chris Young testified during an ongoing hearing in Philadelphia on Monday.

The inside look at how winners were selected is at odds with how Musk himself described the "random" selection process.

"Were you surprised that he used the word 'randomly'?" Philadelphia District Attorney Larry Krasner's attorney, John Summers, asked.

"That's not the word I would have selected," Young said.

Young testified that he reviewed candidates based on the location of Musk's next rally before vetting the people who signed America PAC's petition in support of the First and Second amendments.

Former President Donald Trump is scheduled to host multiple dinners on election night at his Mar-a-Lago club -- including with his close friends, donors and club members, multiple sources familiar with the dinners told ABC News.

Trump is expected to dine with an intimate group of close friends Tuesday night, and there will be a separate Mar-a-Lago club member dinner in the ballroom. A source familiar with the dinners said there won't be any formal speeches but Trump will likely stop by to greet them all.

Earlier that day, Trump is expected to cast his vote in Palm Beach, Florida.

Several of the attendees of the dinners told ABC News that they're planning on heading over to the Palm Beach Convention Center after the dinner.

Harris addressed canvassers in Scranton, Pennsylvania, ahead of a rally later this afternoon in the battleground state, where she emphasized building community and unity.

"I can feel the mood in here because it's the best of who we are as a democracy," Harris said at the event at the Montage Mountain Resort. "We are a people-driven campaign, and we love the people, and we see in the face of a stranger a neighbor, right? And that's the spirit of what we are doing."

She said the "whole era of this other guy" and discussion about "trying to point fingers at each other and divide each other" makes people feel alone.

"As we are getting out to vote, as we are canvassing, let's be intentional about building community, about building community, about building coalitions, about reminding people we all have so much more in common than what separates us," she said.
