(Reuters) -Iranian cyber actors sent messages during the summer to people involved in President Joe Biden's then re-election campaign containing non-public material from Republican presidential candidate Donald Trump's campaign as part of efforts to influence the Nov.

It's "the latest example" of Iran's efforts to "stoke discord and undermine confidence" in the U.S. electoral process, FBI says.

The Iranian government has been tied to an assassination plot on US soil and a hack of the Trump campaign, both of which Tehran has denied.
