“On Friday, U.S. President Donald Trump said he was officially withdrawing his certification of Iranian compliance with the nuclear deal, in what is being billed as part of a tougher strategy on Iran,” according to Oil Price.com. “President Trump passed the nuclear deal back to Congress to review and amend the law.
