In an interview with NBC’s “Meet the Press” that will air Sunday, Ryan said the “toothpaste is already out of the tube” when it comes to the deal.
“I never supported the deal in the first place. I thought it was a huge mistake. But the multilateral sanctions are done,” he said.
“I don’t think you’re going to go back and reconstitute the multilateral sanctions that were in place,” he added.
The deal, reached in July 2015, lifted sanctions in exchange for limits on nuclear activity in Iran.
“I think the key is to rigorously enforce this deal. But also, remember, they’re testing ballistic missiles,” Ryan told NBC.
