Trump's spokesman Sean Spicer said the review would be conducted by U.S. government agencies over the next 90 days and recommendations would be presented to the president as to whether to stick by the deal.
"It shouldn't have been signed". The deal, he said, "fails to achieve the objective of a non-nuclear Iran" and "only delays their goal of becoming a nuclear state".
President Donald Trump accused Iran on Thursday of failing to abide by the "spirit" of a landmark 2015 deal created to allow the nation to pursue a nuclear energy and research program but prevent it from producing a nuclear weapon.
Secretary of State Rex Tillerson notified Congress in a letter on Tuesday that Iran has been complying with its commitments under the JCPOA, and that the administration was considering additional sanctions relief.
"Not only does that defy logic - but it adversely effects American security interests", said Reza Marashi, National Iranian American Council. "He should have said the nuclear deal deals with nuclear issues, and we are going to be very tough in enforcing it, but it doesn't deal with Iran's support for terrorism", Deutch said.
In a scathing assessment, the Secretary of State also accused Iran of exporting terror and violence, and confirmed that Washington is conducting a review of its policy towards the Middle Eastern nation.
Opponents of the deal, including Israel, objected, saying it only delayed Iran's pursuit of nuclear weapons and did not allow for the kind of inspections of its atomic sites that would guarantee it was not cheating.

Iran has yet to comment on the Trump administration's review, but Iranian Supreme Leader Ayatollah Khamenei warned in November that Tehran would retaliate if the United States breached the nuclear agreement.
Mr Tillerson told reporters on Wednesday that the review will not only look at Teheran's compliance with a 2015 nuclear deal, but also its behaviour which undermined U.S. interests in Syria, Iraq, Yemen and Lebanon. "So we will see what happens", Trump said.
Under the deal, brokered by President Barack Obama and other world powers, Iran agreed to roll back key aspects of its nuclear program in exchange for relief from nuclear-related economic sanctions.
If the United States reneges on its obligations under the deal, Iran is likely to follow suit and start expanding its nuclear activities-regardless of who wins the presidential elections. But Iran has not lived up to the spirit of the agreement. But he said its "nuclear ambitions" remained "a grave risk to worldwide peace and security".
According to White House spokesperson Sean Spicer, the review will aim to determine if Iran is in compliance with the deal, then proceed to provide the president with recommendations on the best path to take moving forward.
Iran has also been backing the Syrian government of President Bashar Assad, also sending military advisers and fighters to Iraq to help fight Islamic State (IS, formerly ISIS/ISIL) there.
