US intelligence says Iran hacked the Trump campaign

We have observed increasingly aggressive Iranian activity during this election cycle, specifically involving influence operations targeting the American public and cyber operations targeting presidential campaigns.

This includes the recently reported activities to compromise former President Trump’s campaign, which the [Intelligence Community (IC)] attributes to Iran. The IC is confident that the Iranians have through social engineering and other efforts sought access to individuals with direct access to the presidential campaigns of both political parties. Such activity, including thefts and disclosures, are intended to influence the U.S. election process. It is important to note that this approach is not new. Iran and Russia have employed these tactics not only in the United States during this and prior federal election cycles but also in other countries around the world.

Protecting the integrity of our elections from foreign influence or interference is our priority. As the lead for threat response, the FBI has been tracking this activity, has been in contact with the victims, and will continue to investigate and gather information in order to pursue and disrupt the threat actors responsible.
