Trump campaign says it was hacked by foreign actors

• The Trump campaign said that a foreign hacker had breached its systems and gained access to internal communications.
• Microsoft published a report dated Friday laying out several Iranian cyberthreats attempting to influence the U.S. presidential race between Donald Trump and Vice President Kamala Harris.
• Politico began receiving leaked Trump campaign documents from an anonymous email account in July.

The Trump campaign on Saturday said that a foreign hacker had breached its systems and gained access to internal communications.

Politico began receiving leaked campaign documents from an anonymous source on July 22, according to the news outlet's report on Saturday. Politico first reported the campaign's acknowledgement of the hack.

"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 spokesperson Steven Cheung said in a statement.

CNBC has not independently verified the source of the hack.

The Trump campaign's statement implied that Iranian hackers were behind the breach but did not provide any direct evidence supporting that claim.

Rather, Cheung cited a Microsoft report dated Friday warning that Iranian hackers had launched several different attempts to influence the U.S. presidential election, including sending a phishing email in June to a high-ranking campaign official from the hacked account of a senior advisor.

Microsoft declined to provide additional comment on whether the Trump campaign had been a target of the Iranian hacking plot.

Earlier this summer, U.S. officials became aware of an Iranian plot to assassinate Trump. Officials learned of the plot in the weeks ahead
