President Joe Biden’s campaign did not reach out to law enforcement after individuals associated with the campaign received hacked material from Donald Trump’s campaign in their personal email accounts, according to officials with the campaign and law enforcement.

The announcement is the latest U.S. government effort to call out what officials say is Iran’s brazen, ongoing work to interfere in the election.

Among the material was research compiled by the Trump campaign on JD Vance and internal polls from the campaign.
