2024 election updates: Millions have voted early as Trump, Harris sprint to finish

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."

The Republican National Committee filed a lawsuit against the Milwaukee Election Commission on Monday, accusing the city agency of "arbitrarily limiting observers" at polling places.

The RNC alleged that the Milwaukee Election Commission limited the number of observers at some early voting sites to only one observer per political party, in violation of state law. During the early voting period, access was limited at three polling locations, according to the lawsuit.

"Interest in this election is at unprecedented levels in American history, as that has generated corresponding interest in observing the voting process in the City of Milwaukee," the lawsuit said.

According to the lawsuit, the Milwaukee Election Commission plans to continue limiting the total number of observers on Election Day depending on the "space, access, number of voters, and other prevailing circumstances" at polling locations.

The RNC is asking the court to order the Milwaukee Election Commission "to allow the public to observe all public aspects of the voting process."

Representatives for the Milwaukee Election Commission could not be immediately reached for comment.

In September, the RNC filed a lawsuit against the city of Racine, Wisconsin for not hiring enough Republican election inspectors for this summer’s primary election.
