2024 election updates: Trump slams Biden over 'garbage' comments, calls opponents 'lowlifes'

In a lengthy post on the social platform X, former Republican Governor of California Schwarzenegger said he "hates" politics more than ever, is not happy with either political party and would prefer to "tune out."

But, he said, he is endorsing Democrats Harris and Walz because "I will always be an American before I am a Republican."

Schwarzenegger went on to harshly criticize Donald Trump for rejecting the results of the 2020 presidential vote.

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.

The campaign filed a writ of summons, which contained no allegations or specific claims.

A spokesperson for Bucks County told ABC News in a statement Tuesday evening that the county "has been made aware that litigation may be filed tomorrow. We have no comment at this time."

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 were purged, however, can still have a chance to vote if they use Virginia's same-day registration option at the polls.

Virginia Attorney General Jason Miyares tweeted on Wednesday "I am pleased to announce that the US Supreme Court granted Virginia's emergency stay to keep noncitizens off our 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,

It's a state that could tip the result of the 2024 election.

And Trump is ramping up rhetoric sowing doubt on the state's voting process.

In a post on his social media site on Wednesday morning, Trump claimed there's "cheating" happening at "large scale levels." He did not elaborate or provide evidence for his claims.

Some isolated incidents have emerged, including approximately 2,500 potentially fraudulent voter registration applications being investigated in Lancaster County, though officials stressed the system worked and that voters can be confident in the election.
