Maximum Pressure Act
Sponsored By: Representative Nunn (IA)
Introduced
Summary
Deny Iran all paths to a nuclear weapon. This bill would use sustained "maximum pressure" through expanded sanctions, tighter banking bans, and new watchlists to block Iran's nuclear, missile, and proxy networks.
Bill Overview
Analyzed Economic Effects
12 provisions identified: 3 benefits, 8 costs, 1 mixed.
Up to $25M for terror tips
You could get up to $25,000,000 for information that leads to the arrest, conviction, or capture of listed terrorists tied to the October 7 attack. The Secretary of State could approve larger rewards when needed and may pay up to twice the amount for tips that help capture a leader.
Keep Iran sanctions until strict steps
This bill would make it much harder to lift Iran sanctions. Sanctions would stay in place until the President certifies Iran met many conditions, and several Iran-related executive orders would keep running. The President would have to send Congress a report before ending, waiving, or licensing major sanctions, and wait 30 days (60 days in late summer) unless Congress approves. It would bar removing the IRGC terrorist label or delisting people from 2019–2021 without that certification, and stop new IRGC-related waivers or licenses. It would also expand human-rights listings and tighten end‑of‑listing rules, with some waiver powers ending two years after enactment.
Limit future waivers on Iran sanctions
If enacted, this would sharply curb waiver powers. Existing waivers under certain sector laws would end on enactment, and no waivers under those sections could be issued before February 1, 2028. Two years after enactment, one sector’s waiver authority would end entirely. Starting February 1, 2028, the President would also lose broad IEEPA waiver and license authority for listed Iran sanctions laws and orders.
Tougher sanctions on Iran missiles
The bill would expand sanctions tied to Iran’s missile and drone programs. Within 120 days, sectors that help missile work could be listed, with asset blocks, visa bans, and bank limits starting after 180 days. It would force quick blocking (within 15 days) of those identified as supporters, and block property of named aerospace affiliates and their networks. It would also add ballistic missile acquisition as a sanction trigger and lower the evidence threshold so sanctions are easier to apply.
Tighter bank rules on Iran deals
This would lock in a ban on many transfers to or from Iran when U.S. dollars are used until a strict certification is made. U.S. banks would be barred from big transactions with foreign banks that break these rules, and foreign banks that handle major transactions for blocked persons could lose U.S. correspondent accounts after 180 days. Treasury would add “facilitating” big transactions as a mandatory sanction trigger (rules due in 90 days, effective for activity starting 90 days after enactment) and would review Iranian banks for added sanctions within 90 days and every 180 days. The President could not rescind Iran’s primary money‑laundering designation without certification, and Treasury would order special anti‑money‑laundering measures for banks tied to the Instex mechanism. It would also bar U.S. funds from allocating IMF Special Drawing Rights to Iran.
Wider sector and shipping sanctions
The bill would add many industries to Iran sector sanctions, including iron, steel, aluminum, copper, construction, manufacturing, mining, textile, petrochemical, automotive, and financial. It would also broaden what counts as “significant support” to Iran shipping to include port authorities, charterers, insurers, and others. But it would protect sales of food, farm goods, medicine, and medical devices, and humanitarian aid, from these sector sanctions.
More funds and help for U.S. victims
The President would have 90 days to move certain frozen Iran‑related funds into the U.S. Victims of State Sponsored Terrorism Fund. This could mean more money for eligible U.S. victims, and it would not block later claims by October 7 victims. The Attorney General, with Treasury and State, would also report within 180 days and yearly on how victims with court judgments can find and collect against Iranian assets.
DOJ push to seize corrupt assets
The Department of Justice would start an Iran Kleptocracy Initiative. It would find and expose corrupt Iranian officials and hidden assets, and work with Treasury and allies to freeze, seize, or repurpose assets. It would coordinate prosecutions and send Congress a yearly report on actions taken.
Faster blocking for terror backers
Agencies would have to find and act on people who fund or support terrorist groups within 60 days and then every 60 days. Blocking would be mandatory, not optional. The bill would also make the Houthi designation order act like a law, adding more force to those sanctions.
Public lists of Iran backers
If enacted, the government would publish lists of foreign people and entities that helped Iran’s missile work, plus entities linked to the IRGC even with small ownership or board influence. A report would also name large Iranian companies and banks and assess IRGC ties. The GAO would review these lists, and recurring reports would identify supporters of Iran’s missile and drone programs, including any North Korean links.
Sanctions on Iran arms transfers
If enacted, the President would sanction foreign people who help supply, sell, or transfer arms to or from Iran within 60 days and then every 180 days. Sanctions could block assets and revoke or deny visas. The President would also have to certify every 180 days that people named in certain UN annexes are not aiding Iran’s missile transfers; if not, their property would be blocked within 15 days and their visas denied, with a narrow UN exception for Iran’s head of state.
Sanctions on Iran's Supreme Leader
Within 30 days, the President would have to sanction Iran’s Supreme Leader and related officials and appointees. Sanctions would block assets, ban visas and admission with immediate visa revocation, and allow penalties for violations. People who materially assist, conduct major transactions, or own or control blocked persons, some board members and senior executives, and certain family members would also be covered.

HR703 — Main Street Tax Certainty Act
This bill would permanently preserve the qualified business income (QBI) deduction by removing the sunset provision in Internal Revenue Code section 199A. The change would apply to taxable years beginning after December 31, 2025, so the deduction would be available for 2026 and later tax years. It achieves this by striking subsection (i) of section 199A and setting that effective date. Taxpayers with qualified business income would continue to claim the QBI deduction under the existing Section 199A rules for those years.
HR452 — Miracle on Ice Congressional Gold Medal Act
This law awards Congressional Gold Medals to the 1980 U.S. Olympic Men's Ice Hockey Team as a formal recognition of their Lake Placid victory and its lasting effect on American morale and the sport of hockey. It directs the Treasury to strike the medals and sets rules for duplicates, display, and funding. - Team legacy and public recognition: The Act honors the 1980 team with a symbolic national award that reinforces their historical and cultural significance for fans, players, and communities connected to the game. - Museum displays and research access: One gold medal goes to the Lake Placid Olympic Center, one to the United States Hockey Hall of Fame Museum in Eveleth, Minnesota, and one to the United States Olympic & Paralympic Museum in Colorado Springs for display and research. - Mint operations and collectibles: The Secretary of the Treasury will strike the medals, may sell bronze duplicates at prices that cover costs, and classifies the medals as national and numismatic items. The U.S. Mint Public Enterprise Fund pays for production and receives proceeds from duplicate sales.
HR1422 — Enhanced Iran Sanctions Act of 2025
Targets Iran's energy revenue through global sanctions. This bill would create a broad sanctions framework to punish foreign persons who process, export, or sell Iran-origin oil, condensates, gas, LNG, or petrochemical products. It pairs blocking of assets and visa bans with ownership-based triggers, waivers, humanitarian carve-outs, and new reporting to limit Iran's access to energy markets and finance for weapons and terrorism. - Foreign energy firms and financial institutions would face blocking of property and bans on transactions if they knowingly handle Iran-origin energy or are 50% or more owned by such actors. Associated aliens could become inadmissible and have visas revoked. - Maritime operators, insurers, flag registries, and LNG pipeline facilities would be exposed to sanctions risk when linked to Iran-origin shipments, though safety-of-crew rules and specific exemptions for imports remain. - Humanitarian organizations would keep explicit exemptions for agricultural commodities, food, medicine, medical devices, and humanitarian assistance to avoid disrupting aid. - U.S. agencies and private companies would see new duties: an interagency working group and multilateral contact group would coordinate enforcement, and private-sector reporting would be required to flag evasion and proceeds from intercepted Iran-origin energy sales.
HR842 — Nancy Gardner Sewell Medicare Multi-Cancer Early Detection Screening Coverage Act
Would expand Medicare to cover multi-cancer early detection screening tests. It defines eligible tests as certain FDA-cleared or approved genomic blood tests or comparable biological-sample tests and directs the Secretary to use the national coverage determinations process to decide when they are covered.
HRES719 — Honoring the life and legacy of Charles "Charlie" James Kirk.
Condemns political violence. The resolution condemns the assassination of Charles 'Charlie' James Kirk, honors his life and leadership, and urges swift justice while offering sympathy to his family.
HR979 — AM Radio for Every Vehicle Act of 2025
This bill would require AM broadcast capability to be installed as standard equipment in passenger motor vehicles. It focuses on driver-accessible AM reception, allows digital AM audio to count for compliance, and links vehicle AM capability to emergency alerting through IPAWS. - Drivers and households: Built-in, driver-accessible AM reception would make it easier for people to get local AM stations and emergency alerts from their vehicles. The bill allows devices that receive digital AM to meet the requirement. - Vehicle manufacturers: The Department of Transportation would need to issue a rule within 1 year, with a general compliance deadline no later than 2 years after the rule is issued. Small manufacturers that produced no more than 40,000 passenger vehicles in 2022 would get at least 4 years to comply. - Oversight and emergency systems: States would be barred from imposing their own AM-access rules. The bill mandates interim labels and pricing protections for cars without AM, authorizes civil penalties and DOJ injunctions for violations, requires a GAO study and a congressional briefing within 1 year, and includes an 8-year sunset for the authority.
