The White House said Thursday night that Vice President JD Vance was delaying a trip to Switzerland to lead a new round of negotiations with Iran over its nuclear program — raising questions about what’s next for the tentative agreement to end the war.

It said the team lead by Vance had been ready to leave but was postponing, citing difficult logistics for negotiations. The announcement followed a report from Al-Mayadeen, a pan-Arab satellite channel that is politically allied with the Iranian-backed Lebanese militant group Hezbollah, that Iran was delaying sending its delegation to Switzerland over Israel’s ongoing military campaign in Lebanon.

The postponement came after the U.S. said it had lifted its blockade, allowing oil tankers to begin freely moving through the Strait of Hormuz after months of being unable to use the critical channel. But the initial agreement has drawn sharp criticism from some in the U.S. — including a few congressional Republicans — who worry Washington ceded too much to Iran with relief from sanctions and a potential $300 billion fund to help with rebuilding.



Earlier, Vance took the relatively unusual step of appearing at the White House to defend the deal, arguing that while it offers concessions, Iran first has to comply with U.S. demands.

“As they dial up their good behavior, we can dial up the economic relief,” Vance said. “If they dial down their good behavior, we can turn it off.”

The vice president had said during those remarks that he was not sure of the timing of the planned trip to Switzerland, and the postponement makes that even less clear.

A top Trump administration envoy told U.S. lawmakers in a private briefing that Iran will invite the U.N.’s nuclear watchdog agency to inspect its nuclear sites. And Iranian Supreme Leader Ayatollah Mojtaba Khamenei had seemed to endorse direct negotiations for his officials.

“It is obvious that the face-to-face negotiations that will be held in the future will not mean accepting the enemy’s opinion,” he said in a statement read by state media.
