Vice President JD Vance implored critics of the Iran deal to just “have a little faith” that President Donald Trump would not screw this up.Vance has been pulling double duty, leading the Trump administration’s messaging campaign backing the memorandum of understanding and touting the release of his own book, a reflection on his journey to Catholicism. The vice president appeared Thursday in the briefing room to answer the latest questions on the peace process and defend the White House’s own murky timeline on the proceedings.Vance, alongside Steve Witkoff and Jared Kushner, had helmed the final negotiations with Iran, and he explicitly told reporters that he planned to lead the U.S. side through the next phase of talks.

The MOU itself sets a 60-day window to hash out specifics regarding the future of Iran’s nuclear program, a timeline that Vance clarified and committed to having started on Thursday, following Trump’s signature while dining at the Palace of Versailles in France on Wednesday night.Furthermore, the vice president said that, despite the upended signing schedule, he still expected to travel to Switzerland at some point this weekend to sign the documents himself, noting that he was trying to sync up his timing with the Iranian delegation.“It just depends on exactly when the Iranians can get there,” Vance said. “We’re trying to figure that out as we speak. We’ll find out exactly when over the coming days.”
