Referred to the Committee on Foreign Affairs, and in addition to the Committees on the Judiciary, Ways and Means, Oversight and Government Reform, Financial Services, Rules, and Intelligence (Permanent Select), for a period to be subsequently determined by the Speaker, in each case for consideration of such provisions as fall within the jurisdiction of the committee concerned.
Sponsored by Zachary Nunn (R-IA)
What it does
This bill would codify and expand U.S. sanctions on Iran, including mandatory sanctions on Iran's Supreme Leader and his office, expanded sectoral sanctions (adding sectors like steel, automotive, and financial), and restrictions on the President's ability to waive, lift, or terminate sanctions without certifying that Iran has met 12 specific conditions (ending nuclear enrichment, ballistic missile development, support for terrorism, and more). It would repeal the sunset provision in the Iran Sanctions Act of 1996, require any future agreement with Iran to be submitted to the Senate as a treaty, restrict funding for U.S.-Iran diplomatic engagement in certain circumstances, and create new reporting requirements and a fund tied to frozen Iranian assets for terrorism victims.
Who benefits
U.S. victims of Iran-linked terrorism who may gain expanded access to frozen Iranian assets through a new compensation fund; Israel and other regional partners who view Iran's nuclear and missile programs as a security threat; members of Congress who gain greater oversight over future U.S.-Iran diplomatic agreements; human rights advocates for Iranian dissidents.
Who is hurt
The President and executive branch, whose flexibility to waive or lift sanctions for diplomatic negotiation is significantly curtailed; U.S. companies and foreign firms in newly covered sectors (steel, automotive, financial, etc.) that trade with Iran and would face new sanctions exposure; foreign banks and businesses dealing with Iranian counterparts who risk secondary sanctions; Iranian civilians who could face continued economic hardship from broadened sectoral sanctions, despite humanitarian exceptions for food and medicine.
Supporters argue
Supporters argue that Iran's nuclear enrichment has reached levels with no civilian justification, its ballistic missile arsenal is the largest in the Middle East, and past sanctions relief under the JCPOA funded terrorist proxies rather than moderation, citing IAEA reports of 275 kilograms of 60%-enriched uranium. They contend that locking sanctions into statute and requiring Senate treaty ratification of any future deal prevents any future administration from unilaterally granting relief without verified, permanent changes in Iranian behavior.
Opponents argue
Opponents argue that eliminating presidential waiver authority and requiring near-total Iranian compliance with 12 sweeping demands before any sanctions relief removes the diplomatic flexibility past administrations of both parties have used to de-escalate crises and secure hostage releases. They contend that expanding sectoral sanctions to include steel, automotive, and financial sectors risks broader unintended harm to Iranian civilians and complicates cooperation with allies who maintain separate trade relationships with Iran.
Constitutional context
The bill touches the constitutional division of foreign affairs authority between Congress and the President: Congress has clear power to regulate foreign commerce and impose sanctions, but binding the President's waiver discretion and requiring that any future Iran agreement be submitted as a treaty raises separation-of-powers questions similar to those addressed in Zivotofsky v. Kerry (2015), which affirmed exclusive presidential authority over some foreign relations functions even against contrary congressional statute.
Checks and balances
Congress would gain significant control over sanctions policy by statutorily restricting presidential waiver authority and mandating congressional certification requirements, narrowing the executive's traditional latitude in foreign affairs and diplomacy.
Historical precedent
The Iran Sanctions Act of 1996 and the Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010 established the sanctions framework this bill amends and expands, and the 2017 Countering America's Adversaries Through Sanctions Act similarly codified congressional review of executive sanctions relief.
