President Trump is expected to refuse to certify Iran’s compliance with the 2015 nuclear-weapons agreement as early as next week, The Washington Post reports. Citing sources familiar with the matter, the report said Trump plans to declare that the landmark agreement with Tehran is not in the national interest of the U.S. The president’s decertification would hand over key decisions on the matter to Congress, which could reinstate sanctions against Iran following a 60-day review. The decision would stop short of scrapping the landmark deal entirely but could be seen as a violation, since the accord calls for an international consensus of Iran’s noncompliance in order to reimpose sanctions. Trump has long hinted at wanting to get out of the agreement, having repeatedly accused Iran of fostering terrorism. Sources familiar with the matter said the president will likely announce his decision in a speech laying out a wider strategy for Iran tentatively scheduled for Oct. 12.
