Trump's campaign is complaining that they were hacked and are blaming the Iranians. Well, it wouldn't be Putin's Russia this time. Anyway, apparently stuff has been shared that the campaign was concealing. According to the Daily Beast it is Trump’s 270-Page Dossier of JD Vance’s ‘Vulnerabilities’ Hacked by Iran
The Trump campaign announced it had been hacked by “foreign sources” that leaked internal documents to news organizations. Iran is the prime suspect.

What you didn't hear this year was anyone in the Harris campaign challenging foreign actors to dig up stuff on the opposition. In 2016 Russia hacked the Clinton site right after Trump asked them to. The odd thing about the Trump claim appears in this tidbit:

The Trump campaign accused Iran of a hack-and-leak operation Saturday, after a 270-page dossier of JD Vance’s “vulnerabilities” was sent to at least two news organizations.

The internal campaign vetting report on Vance was sent to Politico and The Washington Post from an AOL.com email address, along with a document on Marco Rubio, the Florida senator who was not chosen as Donald Trump’s running mate.

Hours after Politico revealed it received the materials, the Trump campaign said it had been hacked, accusing Iran of the breach.

“The Iranians know that President Trump will stop their reign of terror just like he did in his first four years in the White House. Any media or news outlet reprinting documents or internal communications are doing the bidding of America’s enemies and doing exactly what they want,” Trump spokesman Steven Cheung told NBC News.

The irony is stunning, isn't it? Shoe is on the other foot now.

Trump stopped the nuclear treaty with Iran, something that John Kerry had worked long and hard to set up during the Obama administration. Trump set them up to expand their nuclear program now, resulting in sanctions against Iran in this administration for the behavior. Trump is not necessarily their friend, but I doubt he's going after them, either.

Regardless of that, it is out there after someone hacked it. A little more detail from the Daily Beast (not the best source, but not behind a paywall so most readers of this thread can go to the original link):

He went on: “On Friday, a new report from Microsoft found that Iranian hackers broke into the account of a ‘high ranking official’ on the U.S. presidential campaign in June 2024, which coincides with the close timing of President Trump’s selection of a vice presidential nominee.”

The Biden administration has not commented on the alleged hack.
