Republican presidential candidate Mike Huckabee has denounced the Iran deal in controversial terms, invoking the Holocaust by accusing President Obama of “march[ing Israelis] to the door of the oven.” The head of the Democratic National Committee, Debbie Wasserman Schultz, has called for Huckabee to apologize. Congress is now one week into its 60-day period to review the historic deal between Iran, the United States and five other world powers.
