Even more than the actual deal, Mr Trump detests the certification requirement, which forces him to sign off every three months on an accord he has called the worst deal ever negotiated by the U.S., according to the officials.
The other signatories to the JCPOA - the UK, France, Germany, Russia, China and Iran, have said it is not realistic to try to renegotiate its terms.
Mr. Trump has until Sunday to decide whether to recertify that Iran is in compliance with the Obama-era nuclear agreement, which limits Iran's nuclear program.
Serious concern has been growing on the possible U.S. administration's withdrawal from Iran nuclear deal.
Many disagree Iran is in compliance with the JCPOA, including Senators Tom Cotton, R-Ark., Ted Cruz, R-Texas, David Perdue, R-Ga., and Marco Rubio, R-Fla., who spelled out major instances of Iranian noncompliance and cheating in a July 11, 2017 letter to Secretary of State Tillerson.
It's Now Trump, Pence and Cowboys' Jerry Jones vs. the NFL
Some states have their own First Amendment-style protections, and they can include protection of political speech, Tushnet said. President Donald Trump has been pressuring NFL owners to discipline players who do not stand for the national anthem.
Last month, Trump, during an address before the United Nations General Assembly, said, "The Iran deal was one of the worst and most one-sided transactions the United States has ever entered into frankly that deal is an embarrassment to the United States, and I don't think you've heard the last of it".
France, Germany and Britain, despite their opposition to Washington backing away from the deal, have told US lawmakers that they could join discussions on constraining Iran's long-term nuclear ambitions, according to one congressional Democratic aide.
In anticipation of Trump's announcement this week, advocacy groups are beginning to mobilize in support of the agreement, and in opposition to Trump's reckless moves to undermine and dismantle it.
If the USA backs out of the nuclear deal, "it won't be our failure at all, but a failure for the other side", Rouhani said, according to state TV.
Trump has certified the deal twice, once in April and once in July, although he has said he did not want to do it. "We may have to array our forces to prepare for. calibrated strikes".
Real estate agent's courageous shark rescue caught on camera
Hatheier, an agent with Cronulla Real Estate , was swimming in the pool when she passed over it, Nine News reported . The video was posted on Facebook and has received more than 1,600 reactions and 1,300 shares as of Wednesday.
Federica Mogherini, while talking to PBS TV channel, on Wednesday, highlighted Iran's full compliance with the 2015 deal.
But several key Democrats suggested there might be room to negotiate with Republicans about beefing up the deal without eviscerating it. If those sanctions are put back into place, the JCPOA would be considered breached.
In a Tuesday phone call with British Prime Minister Theresa May, Trump expressed the need to work together "to hold the Iranian regime accountable for its malign and destabilizing activities, especially its sponsorship of terrorism and its development of threatening missiles", according to the White House. But it is a requirement of USA law. He also is expected to target the country's paramilitary Revolutionary Guard with new sanctions. 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 US and its allies.
Worldwide inspectors say Iran is in technical compliance with the accord, but Trump says Tehran is in violation of the spirit of the agreement and has done nothing to rein in its ballistic missile program or its financial and military support for Hezbollah and other extremist groups.
But it could be hard to get both Iran and its ally, Russia, back to the table for a new round of talks. The International Atomic Energy Agency says Iran is complying with the agreement. Congress would act under provisions of the Coker-Cardin Act which allow expedited consideration of taking such action over a 60-day period.
