Former Trump adviser Keith Kellogg told NewsNation on Thursday that Iran’s enriched uranium still needs on-site inspectors to confirm its status.

He served as national security adviser and envoy and said the uranium, rather than a major waterway, was the chief aim of the campaign. U.S. strikes wrecked Iran’s armed forces and navy while drones and ballistic missiles remain available, he added, and Trump became the first president to bury that uranium beneath mountain sites.

Any written deal must let IAEA teams enter all those places in person, Kellogg said, or the work stays unfinished and a nuclear weapon could still be built.
