WASHINGTON — President Donald Trump is holding a White House Situation Room meeting with his advisors to make a final determination on whether to approve a tentative U.S.-Iran deal to extend their ceasefire by 60 days and begin new nuclear talks. U.S. and Iranian negotiators have reached a preliminary agreement that would pause hostilities and restart negotiations on Iran’s nuclear program.

Under the tentative deal, the ceasefire extension would include discussions on the fate of Iran’s stockpile of highly enriched uranium, which stands at 440.9 kilograms enriched up to 60% purity—a level close to weapons-grade. The U.S. would gradually lift its naval blockade on Iranian ports and ease sanctions to allow Iran to sell more of its oil, according to a U.S. official familiar with the matter. In return, Iran would be prohibited from imposing tolls on the Strait of Hormuz and would have to remove all mines from the waterway within 30 days.

Vice President JD Vance said the sides were still negotiating “a couple of issues on the nuclear stuff, the highly enriched stockpile, and also the question of enrichment.” He added that while adversaries had reached a tentative agreement, they continued to debate “a couple of language points,” and he could not confirm whether Trump would approve the proposal. “We’re in a position where we could substantially set back their nuclear program, not just during the term of this president but over the long term. That’s a very very good thing for the American people,” Vance said in a podcast interview.

Trump has expressed discomfort with one potential solution under discussion: allowing China or Russia to take custody of Iran’s enriched uranium. “I wouldn’t be comfortable,” he said. Iran has not publicly committed to relinquishing its stockpile, which is believed to be buried beneath three nuclear sites damaged by U.S. airstrikes last year.

Iranian Parliament Speaker Mohammad Bagher Qalibaf emphasized his country’s stance on negotiations, saying, “We do not gain concessions through talks, but through missiles. In negotiations, we only make them understand that.” He added, “The winner of any agreement is the one who is better prepared for war the day after it is signed,” and stressed that Iran has “no trust in guarantees or words,” only actions, and “no step will be taken before the other side acts.”
