The FBI has launched an investigation into Donald Trump's presidential campaign claimed his internal communications were targeted by hackers who works for the Iranian government.
The former president said Saturday that Microsoft had notified his campaign that Iran had hacked one of his websites.
Trump said Iran “could only get publicly available information.”
“We can confirm that the FBI is investigating the matter,” the FBI said in a statement Monday, but did not name Trump or Iran.
The Iranian government denies hacking Trump's campaign.
The FBI is also investigating an alleged hack that targeted advisers to the campaign of President Joe Biden and Vice President Kamala Harris, the Washington Post reported Monday.
The FBI began its investigation in June, when Biden was still a candidate for president, on suspicion that Iran was behind efforts to steal data from two U.S. presidential campaigns, the newspaper said, citing sources.
Harris' campaign told NBC News that the FBI notified her in July that she was the target of a “foreign influence operation.”
The campaign said “robust cybersecurity measures are in place” and that “there has been no security breach” as a result of those efforts.
Trump's campaign pointed to a report from Microsoft researchers on Friday that found hackers with ties to the Iranian government attempted to break into the account of a “senior official” of a U.S. presidential campaign in June.
The report found that the hackers took over the account of a former political adviser and then used it to attack the official.
No further details were given about the identities of the targets.
