Iranian hackers sought to interest President Joe Biden’s campaign in information stolen from rival Donald Trump’s campaign, sending unsolicited emails to people associated with the then-Democratic candidate in an effort to interfere in the 2024 election, the FBI and other federal agencies said Wednesday.

There’s no indication that any of the recipients responded, officials said, and several media organizations approached over the summer with leaked stolen information have also said they did not respond. Kamala Harris’ presidential campaign called the emails from Iran “unwelcome and unacceptable malicious activity” that were received by only a few people who regarded them as spam or phishing attempts.
