Trump to make Iran deal decision today: Tillerson

The president has to re-certify the deal today.

"He’s going to get to make that decision this afternoon. We have a session scheduled with him over at the Oval [Office] today," Tillerson told reporters during a photo-op at the State Department Thursday.

As is customary, the Secretary of State has been designated to sign the waivers, which, despite different upcoming deadlines, will be bundled together as one document. Tillerson will be the one to notify Congress of the administration’s decision Friday.

This isn't the first time Trump has had to waive sanctions and keep the Iran deal alive -- but it will be the first time since he announced his new Iran strategy in October and threatened to terminate the deal unless Congress made some "fixes."

In that speech, Trump kept the U.S. in the agreement, but refused to certify the Iran nuclear deal, telling Congress that the sanctions relief to Iran was greater than the advantages to U.S. national security.

European partners have been intensely lobbying Congress and the White House to remain in the agreement, which they see as doing its job and preventing Iran from obtaining a nuclear weapon at this time.

"When you have signed up to an agreement which was negotiated -- my goodness, I mean, it was five years longer if you think about all the talks," Kane added. "Now to say, 'We would like to have a change, or we need to look at it again'... it would be a very hard case to make."
