2024 election updates: Trump and Harris bring their campaigns to the battleground state of Wisconsin

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.

Vice President Kamala Harris and her running mate Gov. Tim Walz will return to North Carolina this week amid early voting.

As of Tuesday, October 29, more than 3.1 million people across North Carolina have cast ballots between absentee and early in-person voting.

Harris will attend a campaign event in Raleigh on Wednesday. The rally will be held at Coastal Credit Union Music Park at Walnut Creek.

Democratic vice presidential candidate Walz will visit Charlotte, Greensboro, and Asheville in a series of events aimed at encouraging North Carolinians to vote early for the Harris/Walz ticket.

Republican vice presidential candidate Sen. JD Vance will also return to North Carolina on Thursday for a town hall event.

The town hall will be hosted by Turning Point PAC and Turning Point Action at High Point University.

Turning Point says many students remain undecided voters even days before the Nov. 5 election. Turning Point said it will work to ensure the audience is "inclusive of students of a broad spectrum of cultural backgrounds and experiences as well as political affiliations."

The Pennsylvania push continues Wednesday in the race for the White House.

Democratic presidential nominee, Vice President Kamala Harris, will hold a rally in Harrisburg on Wednesday.

Republican VP nominee, JD Vance, will lead a rally in Bedford, which is in western Pennsylvania.
