The campaign of Republican US presidential candidate Donald Trump says some of its internal communications have been hacked, blaming the Iranian government and citing past hostilities between Trump and Iran without providing direct evidence.
The campaign statement came shortly after news website Politico revealed it began receiving emails in July from an anonymous source offering authentic documents from inside Trump's operation, including a report about running mate JD Vance's "potential vulnerabilities".
"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," Trump campaign spokesman Steven Cheung said in a statement on Saturday.
Late on Saturday, Trump posted on his Truth Social app that Microsoft had just informed the campaign that Iran had hacked one of its websites.
He cast blame on Iran, adding they were "only able to get publicly available information".
He did not elaborate further on the hack.
Reuters has not independently verified the identity of the alleged hackers or their motivation.
The Trump campaign referred to a Friday report from Microsoft researchers that said Iranian government-tied hackers tried breaking into the account of a "high-ranking official" on a US presidential campaign in June.
The hackers had taken over an account belonging to a former political adviser and then used it to target the official, the report said.
That report did not provide further details on the targets' identities.
A Microsoft spokesperson declined to name the targeted officials or provide additional details after the report was published.
Iran's permanent mission to the United Nations in New York said in an email that "the Iranian government neither possesses nor harbours any intent or motive to interfere in the United States presidential election".
"We do not accord any credence to such reports," it added in response to the Trump campaign's allegations.
On Friday, in response to Microsoft's findings, Iran's UN mission told Reuters its cyber capabilities were "defensive and proportionate to the threats it faces" and it had no plans to launch cyber attacks.
"The US presidential election is an internal matter in which Iran does not interfere," Iran's mission to the UN said.
The former president had tense relations with Iran while in office.
Under Trump, the US killed Iranian military commander Qassem Soleimani in 2020 and withdrew from a multilateral Iran nuclear deal.
"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," Cheung said.
Trump survived an assassination attempt in July.
While there have been no suggestions the suspect was linked to Iran, CNN reported in July that the US had intelligence about an Iranian plot against Trump.
Iran has denied such charges.
Late in July, a senior intelligence official told reporters in a briefing that Tehran and Moscow maintained the same presidential preferences as in past cycles.
According to prior intelligence community assessments, Iranian operatives attempted to tear down the Republican ticket while Russia made efforts to smear Democrats.
