U.S. intelligence officials believe that Iran is trying to sabotage former President Trump’s presidential campaign through online influence operations, according to a press briefing on Monday.

Speaking to reporters, an official with the Office of the Director of National Intelligence (ODNI) said U.S. spy agencies “observed Tehran working to influence the presidential election,” likely because Iranian leaders want to avoid increased tensions with the U.S.

The official didn’t directly say that Iran was trying to undermine Trump, but that American spies “haven’t observed a shift in Iran’s preferences” since 2020, meaning that Iran was still targeting Trump.

During the briefing, an intelligence official also said Iran is utilizing “vast webs of online personas and propaganda mills to spread disinformation,” in addition to different online campaigns.
