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

Two Pennsylvania voters and the state's Democratic Party asked the U.S. Supreme Court on Wednesday to reject a Republican request to block counting of provisional in-person ballots cast by people whose mail-in ballots were not put into a required security envelope.

The Democrats argued the Pennsylvania Supreme Court delivered a "straightforward" decision that state law permits voters whose mail ballots were not counted to "exercise their statutory right to vote provisionally rather than be disenfranchised altogether."

The party contends that the RNC has no standing to bring a challenge in the case because it involves two ballots from the 2024 Democratic primary in which the Republican Party could not have been "injured."

A judge has granted a request from the Trump campaign to extend the deadline to apply for mail-in or absentee ballots in Bucks County, Pennsylvania.

They also argued that the so-called Purcell principle -- of nonintervention by courts close to a voting period -- does not apply to state courts.

The Democrats also said the Republicans' request for segregation and non-counting of provisional ballots would be a "sweeping" intervention and imposition on county boards of election which are not even parties to the case.

The Philadelphia district attorney who is bringing a lawsuit to stop Elon Musk's $1 million voter giveaway asked the judge overseeing the case Wednesday to "enhance its security" for an upcoming hearing in the matter.

DA Larry Krasner said in a new court filing Musk's post about the case on X has "triggered an avalanche of posts." including "antisemitic attacks" against the prosecutor.

One account was "inviting political violence" and posted Krasner's home address, according to the filing.

"These posts, which unquestionable are criminal.... and remain posted on Musk's X website today," the filing states.

Another post read "Krasner loves visitors. Mask up and leave all cellphones at home," according to the filing.

"The directives to 'mask up' and to 'leave all cellphones at home' are to prevent identification of illegal actors by video, by eyewitnesses, and by cellphone geolocation," the filing states.

Representatives for Musk did not immediately respond to ABC News for comment.

The hearing in the case is set for Friday at 10am.

Vice President Kamala Harris held her first of three Wednesday rallies in Raleigh, hammering a message of unity.

Harris encouraged North Carolinians to take advantage of early voting, which ends Saturday in the state.

"We have just six days left in one of the most consequential elections of our lifetime, and we have work to do," she said.

"It is time for a new chapter where we stop ... pointing fingers at each other and instead let us lock arms with one another, knowing we have so much more in common than what separates us," she said.

When a protestor began shouting, Harris spoke about bringing people with opposing views into her tent.

"Unlike Donald Trump, I don't believe people who disagree with me are the enemy. He wants to put them in jail. I'll give them a seat at the table, and I pledge to be a president for all Americans and to always put Americans before myself," she said.

Harris also gave a shoutout to Gen-Z supporters.

"I see the promise of America in all the young leaders who are voting for the first time," she said.

A judge has granted a request from the Trump campaign to extend the deadline to apply for mail-in or absentee ballots in Bucks County, Pennsylvania.

The comes after the Trump campaign filed a lawsuit against the county.

The new deadline for voters in Bucks County is now 5 p.m. on Friday, Nov. 1. This is more than the one-day extension the Trump campaign had asked for.

The deadline in Pennsylvania passed on Tuesday at 5 p.m.

In his one page order, Judge Jeffrey Trauger wrote that Bucks County violated the Pennsylvania Election Code after "turning away voters who sought to apply for a mail-in ballot and receive one in person before the deadline."

He ordered the county to allow anyone who wishes to "apply for, receive, vote, and return a mail-in ballot" before the close of business on Friday.
