President Donald Trump responds to Sen. Lindsey Graham’s skepticism about a new preliminary U.S. agreement with Iran by questioning Graham’s stance at the G7 summit. Trump tells reporters he will “have to talk to Lindsey,” adding that Graham “will be in big trouble,” while also saying Graham is “good” and “fine.” The comments come after Graham publicly expressed concerns about the arrangement, though the specific details of the preliminary agreement and the nature of Graham’s objections are not described in the provided accounts. The reporting reflects that Trump dismisses Graham’s criticism rather than engaging with the substance of the critique. No additional consequences or follow-up actions are outlined in the sources. Overall, the coverage centers on Trump’s remarks that he intends to confront Graham directly about the Iran deal, despite Graham’s reservations.
