President Donald Trump is expected to "decertify" the Iran nuclear deal next week, according to CNN.
Trump plans to send the issue to Congress, which would have a 60 day period in which to determine what to do next. The move would be the first step toward fulfilling Trump's promise to end the Obama-era accord.
The accord, formally known as the Joint Comprehensive Plan of Action, must be recertified periodically by the executive branch, per U.S. law. The administration has previously recertified the agreement twice, despite Trump's campaign promise to bring it to an end.
Trump's formal announcement is expected on Thursday, though that time frame could change, according to White House press secretary Sarah Sanders.
In addition to decertifying the agreement, Trump will outline a strategy for countering Iran on multiple levels, including its ballistic missile system and support for international terrorist organizations like Hezbollah. Critics of the deal slammed the Obama administration for failing to include provisions on terrorism and missiles in the agreement.
The decision to not recertify goes against the advice of many in the administration. Most recently, Secretary of Defense James Mattis told the Senate that he believed the U.S. should maintain the agreement. Secretary of State Rex Tillerson has also expressed support for sticking with the agreement.
Trump's decision is likely to upset the JCPOA's other signatories. French President Emmanuel Macron warned Trump against leaving the accord earlier this year, while the European Union's foreign policy chief Federica Mogherini has also said dismantling the deal "would be irresponsible."
