Former President Donald Trump’s campaign said Saturday that some of its internal communications had been hacked.

The campaign blamed “foreign sources hostile to the United States,” citing a Microsoft report on Friday that Iranian hackers “sent a spear phishing email in June to a high-ranking official on a presidential campaign.” Microsoft did not identify the campaign targeted by the email and declined to comment Saturday. POLITICO has not independently verified the identity of the hacker or their motivation, and a Trump campaign spokesperson, Steven Cheung, declined to say if they had further information substantiating the campaigns’ suggestion that it was targeted by Iran.

“These documents were obtained illegally from foreign sources hostile to the United States, intended to interfere with the 2024 election and sow chaos throughout our Democratic process,” Cheung said. “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.”
