Trump’s campaign on Saturday said in a statement it had been hacked.
Fresh off a newly minted Democratic ticket, Vice President Kamala Harris and her running mate, Minnesota Gov. Tim Walz, are set to go on tour, hitting several battleground states in five days -- alongside them and mirroring their schedule state by state is Republican vice presidential nominee Sen. JD Vance.
On Monday, Harris introduced Walz to a fired-up crowd in Philadelphia; Vance was also in Pennsylvania on Monday. The candidates will campaign next in Wisconsin and Michigan.
Bon Iver will join Harris and her running mate on Wednesday in Eau Claire, Wisconsin -- where the Grammy-winning indie folk band was founded -- for a "special performance" as part of the campaign's battleground state tour, the Harris campaign announced on Monday.

At this moment, Vice President Harris has not decided on a running mate and is still deliberating, according to a source.
More than 10,000 people are expected to attend Harris' rally Tuesday night in Philadelphia, where she'll be joined by her new running mate, according to a source familiar with the plans.
That would make this the biggest event yet for the Harris campaign.
Harris is looking to build off her momentum. Pennsylvania kicks off her swing through seven battleground states in five days.
The pace of her campaign is in stark contrast to Trump's, which has only one rally scheduled this week -- in Montana on Friday.
In her first interview since her husband was named former President Donald Trump's running mate, Usha Vance sat down with Fox & Friends where she discussed her husband's "childless cat ladies" comment that has gained attention recently -- calling it a "quip."
"The reality is, JD made a quote – I mean, he made a quip, and he made a quip in service of making a point that he wanted to make that was substantive," Usha Vance said of the comments her husband made in 2021. "And I just wish sometimes that people would talk about those things and that we would spend a lot less time just sort of going through this three-word phrase or that three-word phrase."
She continued, "What he was really saying is that it can be really hard to be a parent in this country, and sometimes our policies are designed in a way that make it even harder."
She added that her husband "would never ever ever want to say something to hurt someone who was trying to have a family who really was struggling with that."
JD Vance has called the comments "sarcastic."
"Let's try to look at the real conversation that he's trying to have and engage with it and understand for those of us who do have families, for the many of us who want to have families, and for whom it's really hard," Usha Vance said on Monday. "What can we do to make it better? What can we do to make it easier to live in 2024?"
