Later Wednesday, Iranian President Hassan Rouhani, told a Cabinet meeting that Trump's speech will make clear "which is the rebellious government, and which is the side that violates worldwide rules".
Under that pact, Iran agreed to freeze its nuclear program for 15 years in exchange for sanctions relief.
"We got nothing", Trump told Fox News in reference to the 2015 accord negotiated with Iran by the United States and five other world powers.
Several congressional Democrats who split with President Barack Obama to oppose the nuclear agreement with Iran are now urging President Donald Trump to uphold the global accord, arguing that robust enforcement is the best way to counter Tehran's malign behavior in the Middle East.
If Congress does not act, however, it would leave the agreement in place.
Lawmaker Behrouz Nemati warned in comments to IRNA that any new sanctions Trump imposes on the Revolutionary Guard "would mean sanctions against the entire Iranian nation".
"It is important to note that Iran continues to pursue an ambitious rocket and missile technology program which is not affected by the sanctions relief", the document said. In a recent review of Iran's compliance of the deal, the White House found the country to have met the requirements, yet Trump insisted on scrapping the deal, stating it was no longer in the US' security interests.
If Trump does decertify the accord as expected, it would put him at odds with Defense Secretary James Mattis, who last week said Tehran was "fundamentally" in compliance with the agreement and that the USA should stick with the pact. Tom Cotton, would expand the US certification criteria to include items that are also the province of the United Nations nuclear watchdog and require the USA intelligence community to determine if Iran is carrying out illicit activity in facilities to which the International Atomic Energy Agency does not have access.
Sen. Ben Cardin of Maryland, the top Democrat on the Foreign Relations Committee, was one of four Senate Democrats who opposed the Iran nuclear agreement in 2015. "Once it was entered into, once it was implemented, we want to see it enforced".
