Stephen Mull will coordinate Iran deal

Stephen Mull, the former US ambassador to Poland, has been chosen to spearhead the implementation of the nuclear agreement between the US and Iran, U.S. Secretary of State John Kerry said on Thursday. "Steve will lead the interagency effort to ensure that the nuclear steps Iran committed to in the (Joint Comprehensive Plan of Action) are fully implemented and verified, and that we and our partners are taking reciprocal action on sanctions, following the nuclear steps," Kerry said in a statement. Mull  served as the US ambassador to Lithuania and was the deputy chief of mission at the US Embassy in Jakarta, Indonesia. Prior to his swearing-in as ambassador to Poland in October 2012, he served as executive secretary of the State Department. He’ll take over the implementation efforts from Joseph E. Macmanus, who has been serving as the interim coordinator and is the current executive secretary at State.
