It was on Saturday that the ex-president's campaign claimed that the Islamic regime had hacked their email and then stolen and spread sensitive internal documents.
"These documents were illegally obtained from foreign sources hostile to the USA, intended to disrupt the 2024 election," a spokesperson for Trump's presidential campaign told BBC.
The news site Politico reports that in July, they received an email from an anonymous sender containing documents from Trump's organization. They also report that the authenticity of the documents has been confirmed.
"Significant influence"
However, the ex-president's campaign has not provided any evidence that Iran was behind the leak, nor have they provided details or information linking the leak to Iran.
On Friday, the data company Microsoft published a report describing how foreign actors have tried to interfere in this year's presidential election campaign.
"In recent months, we have seen the emergence of significant influence from Iranian actors," the report from Microsoft's Threat Analysis Center (MTAC) states, according to BBC.
The report indicates that Iranian hackers targeted an American presidential candidate in June. Which candidate is not specified, but their campaign reportedly received a message with a credible format.
The goal of the message was to get the recipient to click on a malicious link, according to MTAC.
Steven Cheung, spokesperson for Trump's presidential campaign, states that the event mentioned in the report "coincides with the timing of President Trump's selection of a vice presidential candidate".
On Saturday, Donald Trump wrote on his social media platform Truth Social that Microsoft had informed the campaign staff that Iran had hacked one of the campaign's websites.
Iran denies
Microsoft published a similar report in connection with the 2020 election, with similar conclusions, that Iranian hackers had targeted presidential election campaigns.
Earlier, American security sources had also warned of an Iranian plot to assassinate Trump. However, there is no connection between the warning and the assassination attempt on the ex-president last month.
Iran's UN delegation denies involvement and tells the news agency AP that the regime has neither reason nor motive to interfere in the American presidential election.
