Griffin, the chief national security correspondent at the Pentagon, asked Hegseth whether he had “certainty that all the highly enriched uranium was in the Fordow mountain, or some of it, because satellite photos showed there was more than a dozen trucks there two days in advance. Are you certain none of that highly enriched uranium was moved?”

Pete Hegseth and Jennifer Griffin were colleagues at Fox News Channel. But on Thursday, as defense secretary, Hegseth attacked Pentagon reporter Griffin at a news conference.

Defense Secretary Pete Hegseth called his former Fox News colleague Jennifer Griffin "about the worst" to her face in a clash between the pair at a press briefing on the Iran strikes, at which he chastised the media.
