Iran says it will stop complying with parts of 2015 nuclear deal
Iran said overnight it will stop complying with some parts of the nuclear deal, one year to the day after President Trump walked away from the landmark agreement. Iran’s president also threatened to resume enriching uranium if countries that are still part of the deal do not come up with better terms within 60 days. This week the U.S. began moving B-52 bombers and an aircraft carrier strike group to the Persian Gulf region. David Martin reports.
