Lindsey Graham

President Donald Trump denied Tuesday that his hawkish Republican ally, Senator Lindsey Graham, is doubtful of Iran’s perception of its peace treaty with the U.S.

The South Carolina lawmaker expressed concern Sunday over the potential discrepancy between Tehran’s understanding of the agreement and the Trump administration’s messaging. The president has claimed that Iran is in agreement to end its nuclear program, a major issue the two delegations will reportedly negotiate over the summer.

“I’ll have to talk to Lindsey. He’ll be in big trouble,” Trump joked to reporters in France, where he's attending the G7 summit of world powers. “Lindsey’s good. Lindsey’s fine. He’s not skeptical. He’s just fine.”

Graham said in an X post he would follow the negotiations over Iran’s nuclear capabilities, which the two delegations reportedly plan to address in the 60 days after their Friday treaty signing. The Trump administration, he added, should brief Congress on the agreement’s terms since any nuclear deal with Tehran requires a review on Capitol Hill.

“I will be watching closely the ensuing negotiations regarding Iran’s nuclear program and other matters,” Graham wrote. “I am somewhat concerned that Iran’s view of the agreement seems different than what the American negotiating team is claiming.”

Majid Takht Ravanchi, Iran’s deputy foreign minister for political affairs, told reporters this week that Tehran and the U.S. need to hammer out details about the nuclear program, which he noted could stretch out the 60-day deadline.

“There is a discussion about the construction of nuclear power, there are talks on supplies and Iran’s nuclear needs,” Ravanchi said, according to a translation. “All of these have been pointed out.”

Trump, who has previously ignored congressional obligations, teased Tuesday he could brief Congress on the treaty’s terms.

“I never thought about sending it. I never even thought about it,” the president said. “But I will. I will send it to Congress. I like the idea.”

He has, in his usual fashion, presented the deal as a sweeping win for everyone involved in the war, which started with U.S.-assisted Israeli strikes against Iran’s leadership.

“Many presidents have tried to make Peace with Iran, and all have failed before me,” Trump wrote in a Sunday Truth Social post. “The Leaders of the Region have, for the first time, found a President who can help them achieve real Peace.”

Trump withdrew the U.S. in his first term from an agreement entered by the Obama administration that restricted Iran’s nuclear program.
