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.
Pennsylvania Gov. Josh Shapiro will attend tonight's rally in Philadelphia and "will do everything he can" to support the Harris-Walz ticket, someone familiar with the campaign's thinking told ABC News.

Minnesota Rep. Dean Phillips, who was one of President Joe Biden's few primary challengers this cycle, said in a post on X on Tuesday morning that he was "thrilled" by the reports that his "friend" Tim Walz would be Kamala Harris' VP pick.
"I'm thrilled by reports that my friend and governor will be America's next Vice President," Phillips posted, along with a photo of them together.
"Tim is a common-sense, competent and experienced leader whose refreshing normal-ness will be a great contrast to the tiresome weirdness. Let’s go!" he wrote.
Walz and Phillips never served in the House of Representatives together. Walz left his 1st Congressional District seat in 2019, when Phillips was coming in to serve the 3rd District.
Phillips has endorsed Harris' White House bid.

Progressive Minnesota Democrat Rep. Ilhan Omar congratulated her state's governor on Tuesday.
"Our North Star state Governor has signed universal school meals, paid family and sick leave, marijuana legalization, and protections for reproductive rights into law," she wrote on X, also sharing a photo of the two.

Former House Speaker Nancy Pelosi reacted on "Morning Joe" to the news that Vice President Kamala Harris is poised to pick Minnesota Gov. Tim Walz as her running mate, saying: "Tim Walz is wonderful, and she had many good choices."
"Tim Walz, I know very well. He served in the House. To characterize him as left is so unreal. It's just not -- he's right down the middle. He is a heartland of America Democrat. He was the chair of our Veterans' Affairs Committee, and I don't want anybody to forget that -- he made tremendous, tremendous gains for our veterans," Pelosi said.
"We made more progress that has ever been made in the history of our country since the GI Bill under his leadership," she continued.
Pelosi complimented his background and credentials, including serving in the National Guard.
"So, he brings the security credential. He brings the rural credential. And he will do in rural America," Pelosi said.
"So it's really mystifying to me to see someone that I worked with, shall we say, right down the middle characterized on the left in his regard. He has [Harris'] confidence obviously," she added.
"[Walz] has a great vision for our country. It is about working-class families, about rural America, about our veterans. He has won for governor two times in Minnesota," Pelosi added.
