President Trump on Thursday criticized the nuclear deal with Iran just day after his secretary of state certified that Iran was complying with the terms of the agreement, calling it “terrible” and “as bad as I've ever seen negotiated.”
The article also quotes Trump regarding the nuclear sabre-rattling between the U.S. and North Korea.
