Rouhani U.S. exiting Iran nuclear deal will carry a high cost

Iranian President Hassan Rouhani said Monday that if the Trump administration exits the Iran nuclear deal, it "would carry a high cost for the United States of America."

"I do not believe Americans would be willing to pay such a high cost for something that will be useless for them," Rouhani said of a potential U.S. exit from the deal in an interview with CNN.
