A senior administration official declined Friday to say whether Iran’s new supreme leader, Mojtaba Khamenei, has personally signed off on the current agreement being negotiated between Tehran and Washington, writes CNN.

Asked directly whether Iran’s supreme leader has approved the memorandum of understanding, the official sidestepped the question.

“All we can take is the people, both on the civilian and military side, both of whom have attested that the supreme leader is comfortable with where we are in the negotiation”, they said.

The official emphasized that under Iran’s system, final approval ultimately rests on the supreme leader’s “sign off.”

“All we can do is strike the deal, enforce the deal, and only provide the benefits to Iran when we get the benefits for the American people, and that’s our plan,” the official said.
