A foreign policy adviser to Donald Trump on Thursday said the GOP nominee might modify the controversial Iran nuclear deal rather than throw it out.

�He is going to be revising, reviewing, and maybe trying to modify the Iran deal,� Walid Phares told The Wall Street Journal.

He added that Trump would be open to resubmitting an altered version of the agreement to Congress.

Trump previously has ripped the Iran deal as a �terrible deal.�

The agreement lifted U.S. and international sanctions on Iran in return for concessions from that country on its nuclear program.

President Obama has placed the Iran deal as a centerpiece of his foreign policy, but it was opposed by Republicans and many Democrats.

Phares also said Trump would consult with Congress and federal officials about issues like imposing a ban on Muslims entering the country.

�His position which was strong � in terms of the ban � was based on the fact that the Obama administration � the Obama-Clinton administration � for the last seven to eight years was not able to equip us with systems by which we were able to identify the jihadists.�

Phares also pushed back against attacks from Hillary Clinton, who called Trump �temperamentally unfit� to be president and suggested that he would be prone to using nuclear weapons on a whim.

�I don�t see an unusual Trump presidency as Madame Clinton is explaining where he�s going to go crazy and start pressing buttons right away,� he said. �That�s not going to happen. We have a rational institution here.�
