Many members are demanding for Congress to be briefed on details of the announced US-Iran Memorandum of Understanding (MoU).
The details of the MoU between the US and Iran have not yet been made fully public, but officials on both sides have offered some indications of what may be included; the end of fighting on all fronts, including Lebanon, as well as the opening of the Strait of Hormuz.
Republican Senator John Thune told reporters that he doesn’t know enough about the deal with Iran to comment on it yet, but he expects Congress to be briefed soon.
“We do not have an agreement just yet, so we will see when there is text out there. I’m guessing there will be a high level of interest among our members.”

Thune said that he hopes to receive “more details before Friday.” He also suggested that Congress would likely want to hold some type of vote.
“I think there are some requirements that are triggered because of the nuclear components of the deal, in terms of notification or informing Congress. I know there is probably some expectation that there may be a vote at some point.”

Earlier, Senator Lindsey Graham, Senator Chuck Schumer and Senator Jeanne Shaheen, among others, expressed a desire for Congress to have greater input and be briefed on the deal’s details.

Schumer, the Minority Leader, said, “It’s been nearly 24 hours since Donald Trump announced an ‘understanding’ with Iran, and we still don’t have any details.” He added that Trump must brief Congress and the American people and “explain the details of this deal immediately, and put an end this war once and for all.”
Yassamin Ansari, one of two Iranian-American legislators in the US Congress, cautiously welcomed the announcement of the US-Iran deal, saying that an end to the war is a “positive step,” but noted that Congress has yet to see what has been agreed to. “Congress must have extensive review of any final agreement signed with the Islamic Republic,” the Democratic Congresswoman added.
Ansari also noted that the deal “comes after a conflict that inflicted enormous costs and leaves both the United States and the Iranian people worse off.”
“Tremendous loss of life, international instability, and skyrocketing gas prices. This never should have happened in the first place.”

The Trump administration has been under growing pressure from Republican Iran hawks and Democrats, who have said the agreement is weaker than the Obama-era deal that Trump tore up.
More Democratic lawmakers in the US have criticised the deal Trump announced with Iran, with Senator Richard Blumenthal likening the outcome of the US war on Iran to the UK’s Suez Canal crisis, when British forces invaded Egypt with Israeli and French troops. The conflict is widely thought of as a watershed moment in the decline of the UK as a Middle East power.
“History rhymes. The Suez crisis showed the British what overreach looks like: rash military action, allied rupture, then reversal. Trump’s Iran war draws comparison—rapid escalation, risible gains, and a growing credibility bill that the U.S. keeps paying.”

Congresswoman Ayanna Pressley called the deal “necessary and overdue,” but criticised Trump for supporting Netanyahu’s “barbaric warfare at the expense of communities at home and abroad.” “It’s essential this ceasefire holds & brings meaningful peace to the region,” she stated.
Vance Sheds Light On US-Iran MoU
Meanwhile, US Vice President JD Vance published a video on X, explaining what the “great peace deal” with Iran entails as pressure grows for more clarity.
He said the deal means the Strait of Hormuz opens “immediately” and “ensures that Iran will never have a nuclear weapon.” He stated that if the Iranians make the long-term commitment never to rebuild their nuclear programme, “then they are going to be welcomed into the global economy.”
He added that if they violate those commitments, they are “never going to have the resources to do so.” He went on to describe the deal as a “win-win for the American people.”

Also, the US Vice President told a news agency that the deal to end the war “absolutely” includes nuclear inspectors returning to Iran. He added that while the exact date for their return is still to be agreed upon, he expects it will “happen very quickly.”
Vance added that the UN’s nuclear watchdog, the International Atomic Energy Agency (IAEA), will play a role in destroying Iran’s stockpile of enriched uranium. “One of the core parts of the agreement is that the IAEA and the United States are going to help Iran destroy the highly enriched stockpile, and that is something that is spelled out very clearly in the MoU,” he said.
He also said “benefits will flow” to Iran “if they comply,” adding, “That’s what we hope to see.”
“We want them to behave like a normal country. I want them to have a successful country, but only if they do what’s necessary to commit long term to not building a nuclear weapon.”
