Election security: Officials say 2024 election saw only 'minor' disruptive activities

From the moment he arrived in Milwaukee, after being named former President Donald Trump's running mate, it was clear that one of Sen. JD Vance's primary roles was to help deliver battleground Pennsylvania for the former president.

The day Vance was announced as Trump's vice presidential pick in July, Trump told ABC News Chief Washington Correspondent Jon Karl that he was "going to leave [Vance] in Pennsylvania."

Pennsylvania's importance in this election can't be overstated -- it's a crucial swing state with 19 coveted electoral votes where Trump and Vice President Kamala Harris are neck and neck. Whoever wins the state is very likely win the presidential election. During the 2020 election, Pennsylvania was the state that sealed the presidency for President Joe Biden.

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.

"I essentially used the petition like a job application," Young said, with America PAC considering the number of eligible voters that the candidate referred to the petition, their personality and social media history.

According to Young, Musk was notified when a candidate was selected. Young also said that winners signed non-disclosure agreements preventing them from talking publicly about their "consulting agreements."

While the testimony contradicts Musk's public statements, Young insisted that the winners "earned" their money by doing work on behalf of the PAC, seemingly supporting the defense argument that the giveaway is not an illegal lottery.

"Anyone who participated in the program knew what they were entitled to for their participation in the program," Young said.

Closing arguments in the hearing will happen after a brief break.

Michigan Secretary of State Jocelyn Benson was asked during a press briefing Monday about the possibility that Trump could declare victory tomorrow before all the votes are actually counted.

"Candidates don’t get to decide who wins elections, voters do," Benson responded. "And so we will keep reminding folks of that truth. Candidates certainly can say and will say whatever they want to say, it doesn’t change the facts. It doesn’t change the tallies of the votes that are cast on paper ballots that will be audited after the fact and securely tabulated throughout the election to ensure the accuracy of the results, whatever those results may be."

Benson added that they "hope and expect and ask all the candidates to respect the will of the people and respect those results, and to not claim something is true when it's not."

In 2020, Trump claimed to have won the election only hours after polls closed on Nov. 3, 2020, before final results were in.

Benson said she and her staff will be debunking false statements and conspiracy theories as they arise, but that "truth and transparency are on our side."

“We’ve seen how completely innocent things can be misused to spread false aspersions about our election, so let's all be vigilant," she said.

She also urged the public to question what they see on social media.

"Don't assume anything that you're seeing from a source other than a trusted voice or an election official has truth until you cross-check it with other sources of information," she said.

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.
