Secretary of State Rex Tillerson certified to Congress that Iran was complying with Joint Comprehensive Plan of Action (JCPOA), or Iran nuclear deal, before a statutory midnight deadline, while also insisting Iran remained "a leading state sponsor of terror through many platforms and methods" and indicating that the Trump administration would evaluate the JCPOA-related suspension of sanctions and whether it was "vital to the national security interests of the United States."

"President Trump… has realized that tearing up a highly complex and multinational agreement is not a wise thing to do at this time," Farideh Farhi, an independent scholar and affiliate graduate faculty member at University of Hawaii-Manoa, told Reason.

"Note that under the Nuclear Agreement Review Act, the president has to provide certification every 90 days. Had the Trump administration not done so, it would have triggered legislative procedures and potential reimpositions of sanctions, which would then declare the U.S. intent to renege on its JCPOA obligations," she added.
