WASHINGTON, Aug 13 (Reuters) - Vice President Kamala

Harris' presidential campaign said it was notified by the FBI

last month that it was "targeted by a foreign actor influence

operation," a campaign official said on Tuesday.

"We have robust cybersecurity measures in place, and are not

aware of any security breaches of our systems resulting from

those efforts," the official said, adding that the campaign

remains in communication with authorities.

The FBI did not immediately respond to a request for

comment.

The bureau said on Monday that it was investigating after

Republican rival Donald Trump's presidential campaign said that

it had been hacked.

The Trump campaign blamed Iran and pointed to a Friday

report from Microsoft ( MSFT ) researchers that indicated that

Iranian government-tied hackers tried breaking into the account

of a "high-ranking official" on a U.S. presidential campaign in

June.

The Iranian government has denied hacking the Trump

campaign.
