A Pennsylvania judge swiftly granted a request from the Trump campaign to extend the in-person mail-in-ballot deadline in Bucks County by three days -- extending it to the end of the day on Friday.

The campaign had asked for one-day extension.

In his one-page order, Judge Jeffrey Trauger wrote that the 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" to be able to do so before the close of business on Friday.

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.

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.
