The Trump campaign sued Pennsylvania's Bucks County Board of Elections and others Tuesday night over claims the county "turned away voters," according to a filing in the Bucks County Court of Common Pleas.

In a 21-page filing, the Trump campaign claimed voters in Bucks County were "turned away, and forced by security to leave" long lines while attempting to apply in person for a mail-in ballot in the key swing state -- accusing the county of violating the election code.

The campaign is seeking a one-day extension to the mail-in ballot request deadline -- which ended Tuesday at 5 pm. -- to be extended until the end of day Wednesday for voters to apply in person.

The lawsuit includes signed declarations from three individuals who claim they were turned away Monday afternoon. It was joined by a host of Republican figures and groups, including the Republican National Committee, the Republican Party of Pennsylvania, and Senate candidate David McCormick.

Lawyers for the county entered an appearance on Wednesday, according to the docket.

The county was previously accused of "suppressive and intimidating" tactics, including claiming voters were turned away and lines were closed early.

However, the county pushed back on any suggestion that what occurred in Bucks County amounts to intentional voter suppression.

"Contrary to what is being depicted on social media, if you are in line by 5 p.m. for an on-demand mail-in ballot application, you will have the opportunity to submit your application for a mail-in ballot," the county said in a statement.

The county did acknowledge that there was indeed some "miscommunication" from officials on site.

Those in line applying for on-demand ballots were "briefly told they could not be accommodated," the county said, but added that those individuals were ultimately allowed to submit their applications, according to officials.

In a post on X, the secretary of state's office echoed that sentiment, asking for voters to "be patient."

"Earlier today, we spoke with Bucks County election officials who assured us that every registered voter who goes to their county election office by 5 p.m. today will be provided an opportunity to apply for their mail ballot," the post said. "Please be patient with all county election office staff as they work hard to ensure every registered voter is able to vote in this election," he said.

The U.S. Supreme Court is allowing Virginia to move forward with its purge of 1,600 alleged noncitizens from the voter rolls ahead of Election Day.

The conservative majority's decision -- which was not explained -- reverses rulings by a federal district court judge and a unanimous appeals court panel.

Both had said that Virginia's purge, initiated by an executive order from Republican Gov. Glenn Youngkin, violated federal law prohibiting the "systematic" removal of voters from registration lists within 90-days of an election.

The Supreme Court's decision suggests that the justices acted either under the Purcell principle -- to keep federal courts from intervening in state election administration too close to voting -- or under the belief that Virginia had compellingly argued that the federal law's "quiet period" didn't apply here.

The state advanced the idea that noncitizens -- who were never "eligible" to vote in the first place -- can be removed at any time. It also emphasized in court briefs that anyone erroneously removed as an alleged noncitizen is given two opportunities to correct his or her registration status.

The three liberal justices -- Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson -- indicated they would have kept the purge on hold.

Noncitizen voters are already prohibited from registering to vote for federal and state elections.

The Virginia voters who are eligible to vote but were purged, however, can still have a chance to vote if they use the state's same-day registration option at the polls.

In a phone interview on Fox News on Wednesday morning, Youngkin called the Supreme Court’s decision “a victory for common sense” and the Constitution, and emphasized that voters who attest they are U.S. citizens should cast provisional ballots if they were removed from the voter rolls.

Damon Hewitt, the president and executive director of the Lawyers' Committee for Civil Rights Under Law which led the efforts in Virginia, blasted the decision.

"None of this activity is random. It's all highly orchestrated, but it's also orchestrated with a purpose," he said in a statement,

Former California Gov. Arnold Schwarzenegger announced Wednesday that he was going to vote for Vice President Kamala Harris.

"The Terminator" actor and longtime Republican said in lengthy X post that he didn't like either party now given the divisions and lack of progress from leaders in Washington, D.C.

However, Schwarzenegger said he was "furious" over Trump's refusal to accept the 2020 election, anti-immigrant rhetoric, economic policies and actions on Jan. 6.

"We need to close the door on this chapter of American history, and I know that former President Trump won't do that. He will divide, he will insult, he will find new ways to be more un-American than he already has been, and we, the people, will get nothing but more anger," he said.

"That's enough reason for me to share my vote with all of you. I want to move forward as a country, and even though I have plenty of disagreements with their platform, I think the only way to do that is with Harris and Walz," he said.

Nikki Haley recently said she is ready to campaign for Trump, despite not talking to him since June.

Trump's running mate, Sen. JD Vance, when asked about whether Haley will make an appearance, said Tuesday he would "love" to see her on the trail, but said it was up to her schedule.

Haley was Trump's last major challenger in the Republican primary. Despite hitting him hard in the final weeks of her campaign, she later endorsed him at the Republican National Convention.

And she's continued some criticism of his campaign strategy. During an appearance on Fox News, she said the racist remark about Puerto Rico by a comedian at Trump's Madison Square Garden rally was "harmful" and that the campaign "need[s] to go and tell Puerto Ricans how much, you know, they do value them."

She also said the Trump team had to improve its messaging to women.

"I mean, that this bromance and this masculinity stuff," she said. "I mean, it borders on edgy to the point that it's going to make women uncomfortable. You know, you've got affiliated PACs that are doing commercials about calling Kamala the 'C-word,' or you had speakers at Madison Square Garden, you know, referring to her and her pimps."

"That is not the way to win women. That is not the way to win people who are concerned about Trump style," Haley added.
