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

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.

The nation's largest Muslim civil rights organization has sent out 600,000 text messages to ask American Muslim voters to vote on Election Day. The Council on American-Islamic Relations has been targeting Muslim voters across the country, including those in key swing states.

CAIR has not endorsed a candidate and will not do so as a 501(c)(3) organization. However, CAIR National Executive Director Nihad Awad said in a statement, "Turnout numbers for our community so far are promising, but they need to be much higher. We encourage all remaining American Muslim voters to show up on Election Day."

Acknowledging some Muslim American’s views on the ongoing Israel-Gaza conflict, Awad acknowledged that many may be "disillusioned and frustrated due to U.S. support for Israel's genocide in Gaza."

"But sitting on the sidelines of this election will not help the people of Gaza or anyone else," Awad said. "Elected officials take communities seriously when they fully participate in the political process, including by exercising their right to vote. No matter who you support, showing up to vote is a display of political strength."

In recent months, some Muslim American activists have called on Muslim Americans to mobilize as a way of leveraging the community's power post-election.

Pennsylvania Secretary of State Al Schmidt projected confidence about the security of the election, saying it will be "free, fair, safe and secure," during brief remarks Monday.

Schmidt warned Pennsylvania voters to "remain vigilant" about any last-minute misinformation and disinformation that may try to persuade them not to vote.

Schmidt also seemed to try to set expectations for the timing of results in the key battleground state, reminding people that Pennsylvania has "never" had final official results on election night regardless of when the media have called the state.

"We can't predict what percentage of those votes will be counted on election night," Schmidt said.

He noted that 2 million mail-in ballots have been returned so far, which officials can't begin opening until Tuesday morning.

"That means election officials can't even remove the ballot from their envelope," Schmidt underscored.

He said counties will begin to submit unofficial election results beginning at 8 p.m. ET -- and will continue updating throughout the night and "in the subsequent days."
