The Hill- Former Secretary of State John Kerry used his first �tweetstorm� as a retired diplomat to warn the Senate Foreign Relations Committee on Wednesday to �tread carefully� on legislation regarding the future of the Iran nuclear deal.

�On the Joint Comprehensive Plan of Action (JCPOA), we engaged in an important back and forth. And I welcomed that debate,� Kerry wrote, referring to the Obama-era deal negotiated between the U.S. and five global powers with Tehran.

The former Obama administration official cited�Iranian President Hassan Rouhani�s recent reelection, which was largely seen as a referendum on Iran�s nuclear deal, in pushing back against any calls for "a new Iran bill."

�After Rouhani�s reelection, there is much up in the air/room for misinterpretation. This is not the moment for a new Iran bill,� Kerry tweeted.

The Senate Foreign Relations Committee is slated to debate Thursday on expanding sanctions against Iran over its nuclear program.


The State Department informed Congress in April that Iran was in compliance with the 2015 nuclear deal, and that the U.S. would continue to ease sanctions under the agreement.


Under the deal, the U.S. and other nations said they would lift sanctions on Iran if Iran toned down its nuclear program.

Doing away with the agreement was one of President Trump�s key campaign promises. He has ordered a full review of the deal.
