Iran sent messages to people involved in Biden's re-election campaign with material from Trump's campaign as part of efforts to influence the election, U.S. intelligence said.

Morgan Finkelstein, spokesperson for the campaign of Vice President Kamala Harris, which replaced the Biden campaign, said in a statement Wednesday that “we have cooperated with the appropriate law enforcement authorities since we were made aware” of the information being sent to Biden campaign personnel.

The FBI and other U.S. intelligence officials say Iranian hackers stole information from Donald Trump's campaign and sent it to people connected to President Biden's reelection campaign, though federal officials added there's no evidence the recipients of the stolen material even responded.
