U.S. senators from both political parties said Tuesday they had yet to see the text of a [memorandum of understanding struck over the weekend to end the war in Iran](https://nebraskaexaminer.com/2026/06/16/repub/republicans-in-us-senate-left-in-dark-by-trump-on-iran-deal-but-want-details-and-a-vote/), though several indicated any final agreement will require congressional approval.

[Trump and Iranian officials signed the initial deal](https://www.congress.gov/bill/114th-congress/house-bill/1191/text), which [aimed to end fighting and reopen the Strait of Hormuz](https://www.npr.org/2026/06/15/nx-s1-5858590/us-iran-announce-initial-deal-end-war-reopen-strait-hormuz) after more than three months of military conflict. The agreement establishes a 60-day framework for negotiators to reach accord on additional specifics, including Iran's nuclear ambitions.

Senate Majority Leader John Thune, R-S.D., said administration officials have signaled they expect to share the text with lawmakers, though he didn't know when. "Hopefully that'll happen sooner rather than later," he said. President Donald Trump, speaking from the G7 convention in Europe, said he may hold a press conference in "a couple days" to release the text and appeared ready for a congressional vote.

The 2015 Iran Nuclear Agreement Review Act requires the Trump administration to submit the text of any deal addressing Iran's nuclear program within five days to congressional leaders and eight relevant committees. That transmission triggers a 30-day review period during which the Senate Foreign Relations Committee and House Foreign Affairs Committee can hold hearings.

North Dakota Republican Sen. John Hoeven said he believes the plan is to have Congress ratify the Iran agreement. "I think anytime you have Congress ratify something, it gives it longevity," Hoever said. "You can't have the next president come in and change it with an executive order."

Louisiana Republican Sen. Bill Cassidy said he believes an agreement with Iran would represent a treaty subject to Senate approval, requiring a two-thirds threshold under the Constitution. North Carolina Republican Sen. Thom Tillis echoed that sentiment, criticizing President Barack Obama for not seeking Senate ratification of the 2015 Joint Comprehensive Plan of Action, known as the JCPOA.

Connecticut Democratic Sen. Chris Murphy expressed skepticism about the deal itself, saying that "if it is" real, lawmakers should expect "side deals" the administration may not share. "If what's reported is real, it's Iran's terms," Murphy said. "It's essentially a surrender."
