Several media outlets have pointed to White House sources who expect the president to decertify Iran's compliance with the deal, which Trump has called "catastrophic" for the U.S., Israel and the Middle East.
Officials familiar with the internal deliberations as well as informed sources outside the administration say they expect Mr Trump to tell lawmakers that the Iran deal is not in the U.S. national security interest despite Iran's technical compliance.
Notably, the committee's top Republican, Rep. Ed Royce, said the US should adhere to the deal.
Under the 2015 deal, Tehran agreed to roll back its nuclear program in exchange for relief from wide-ranging oil, trade and financial sanctions that had choked the Iranian economy.
In Britain, Prime Minister Theresa May urged the United States on Wednesday to extend the nuclear deal, saying it is "vitally important for regional security". Tom Cotton (R-Ark.)-should be enough to conclude that the president's expected move is a bad idea. He held USA government national security positions for 25 years with the CIA, DIA, and the House Intelligence Committee staff. Fleitz also served as Chief of Staff to John R. Bolton when he was Under Secretary of State for Arms Control and International Security in the George W. Bush administration.
Instead, these officials said Mr Trump is more inclined to throw the matter to Congress and push legislators to amend the law that requires the president to certify Iran's compliance every 90 days.
Iran deal supporters mostly want the U.S.to remain in the agreement because they claim Iran is in compliance and a USA withdrawal would alienate America's European allies.
JCPOA is a "non-binding political agreement".
"The decertification is an essential first step to persuading the Europeans that the alternatives to fixing the deal could be President Trump's decision to abandon the deal", said Mark Dubowitz, CEO of the Foundation for Defense of Democracies, a nonpartisan policy institute. Those provisions relate to enriching uranium to levels near those needed to produce the fuel for a nuclear weapon, as well as other activities that limit Iran's atomic capabilities at various sites. "Once it was entered into, once it was implemented, we want to see it enforced".

But Iranian officials have already ruled out any renegotiation of the deal.
The reversal underscores deep concerns among lawmakers that Trump will inform Congress in the coming days that the landmark 2015 agreement with Iran is contrary to America's national security interests. If those sanctions are put back into place, the JCPOA would be considered breached.
How would the European Union and Iran react to a possible US withdrawal?
Iran's intelligence service and the Islamic Revolutionary Guard Corps "are the cudgels of a despotic theocracy, with the IRGC accountable only to a Supreme Leader".
By moving unilaterally to scrap the agreement against the advice of many members of his own cabinet, the other nations that signed the deal, and most of the world, Trump is "undermin [ing] the credibility of the United States in all manner of negotiations, making it unlikely-to take just one risky example-the standoff with North Korea will be resolved by peaceful means". That could include Iran pulling out of the deal as well and restarting uranium enrichment activities, or Iran could stay in the deal and try to drive a wedge between the USA and its allies.
In this environment, many Democrats believe working on the periphery of the deal could be the congressional equivalent of destroying the village to save it.
"We did it out of weakness when actually, we have great strength", said Trump.
But it could be hard to get both Iran and its ally, Russia, back to the table for a new round of talks. The requirement for certification that Iran is complying with the deal came out of the dissatisfaction by Republicans over the Obama administration's agreement.
