A group of Republicans in the House of Representatives is demanding the Biden administration have Congress review and assess any new nuclear deal with Iran, citing a 2015 law. 

Rep. Michael McCaul of Texas and other Republicans on the House Foreign Affairs Committee wrote US Secretary of State Antony Blinken on Monday. 

“We are writing to remind you of the Administration’s statutory obligations to provide Congress with an opportunity to review and assess any nuclear agreement that you reach with Iran,” they wrote in the letter. 

US officials are negotiating a possible return to the 2015 Joint Comprehensive Plan of Action (JCPOA), more commonly known as the Iran nuclear deal. The agreement, which came into effect under President Barack Obama, removed international sanctions on Iran in exchange for Tehran scaling back its nuclear program. Former US President Donald Trump withdrew from the JCPOA in 2018 and reimposed sanctions. President Joe Biden is now seeking a potential return to the deal. Indirect talks between the United States and Iran in Vienna have been ongoing since April.
