WASHINGTON (AP) — The Obama administration moved on two fronts Monday to advance its nuclear diplomacy with Iran, with talks between top U.S. and Iranian diplomats and an aggressive effort to sell the emerging deal to skeptical American lawmakers and constituencies. U.S. Secretary of State John Kerry and Iranian Foreign Minister Mohammad Javad Zarif met at the residence of Iran's ambassador to the United Nations in New York for the first time since April 2, when world powers and Iran sealed a framework agreement that would limit Iran's ability to build a nuclear weapon.
