July 18 (Reuters) - Iran’s Supreme Leader Mojtaba Khamenei said in a written statement on Saturday that repeated U.S. breaches of a memorandum of understanding signed by the presidents of Iran and the United States had shown that President Donald Trump’s signature was “utterly worthless and devoid of credibility.”
