A bipartisan group of 22 House lawmakers is urging President Donald Trump to fully implement the new Russia sanctions law and revoke a license allowing certain Russian diesel transactions. In a letter sent on 15 October, they copied Secretary of State Marco Rubio and Treasury Secretary Scott Bessent and requested details on planned sanctions, tariffs and waivers.

Their request comes as the law’s first requirements fall due on 18 October, while lawmakers from both parties challengethe administration’s decision to allow certain Russian diesel transactions. Some restrictions take effect automatically, while others require presidential action. The law does not specify a penalty for the president missing the deadline.

What the Russia sanctions law requires

Congress passed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 by votes of 86–11 in the Senate and 262–159 in the House. Trump signed it on 18 September. Graham, a Republican senator from South Carolina, died in July.

Restrictions taking effect automatically on 18 October include a ban on US banks and broker-dealers processing transfers to or from the Russian government, a ban on new US investment in Russia, a ban on new US investment in Russia’s energy sector, and a ban on US energy exports to Russia.

Other measures require presidential action by the same date. The law directs Trump to review and sanction Russian officials, oligarchs and shadow-fleet vessels, sanction the Bank of Russia, specified Russian banks and state-owned companies, and impose tariffs of up to 500% on Russian goods. Tariffs of up to 100% can apply to goods from countries among the five largest importers of Russian oil or gas, or among the top five countries facilitating Russian oil sanctions evasion.

Trump may waive sanctions, restrictions and tariffs under the law if he first certifies in writing to Congress that a waiver is in the US national interest and submits a report explaining its basis.

The diesel license at the center of the dispute

House members also urged Trump to revoke General License 135, which the Treasury Department issued on 9 October and that is valid until 7 April 2027. It permits certain transactions involving Russian-origin diesel, including imports into the United States. Trump said Russia would immediately supply more than 300,000 tons of diesel to US and global markets and predicted prices would fall sharply, according to a 9 October Truth Social post.

On 13 October, a bipartisan group of 12 senators also urged Trump to rescind the deal and revoke the license. Seven senators said the deal conflicted with a 2022 law banning Russian energy imports.

The Graham Act says nothing in its provisions affects the Treasury secretary’s existing authority to issue general licenses. That provision does not resolve whether the diesel license complies with the separate 2022 law.

A White House official told Newsweek the administration would comply with the Graham Act. Bessent said the administration would use “all the legal authorities we have” and called the deal “good for the American people,” Fox News reported on 11 October.

How the sanctions could be lifted

Separately, the law sets a process for terminating sanctions, restrictions or duties against Russia. Trump must report to Congress that Russia has signed a peace agreement accepted by Ukraine’s government and ceased military hostilities against Ukraine, as well as activities to overthrow, dismantle or subvert its government. Congress has 30 days to block termination through a joint resolution of disapproval, or 60 days for reports submitted between 10 July and 7 September.

Seven US senators from both parties said the Trump administration's decision to authorize Russian diesel imports conflicts with a 2022 law banning Russian energy imports and accused it of failing to consult Congress, in a statement on 11 October.

The dispute comes as the war with Iran drives up US fuel prices, which US President Donald Trump has blamed on Ukraine's strikes on Russian refineries. Trump says Russian supplies will help bring prices down, while lawmakers warn that purchases could provide Moscow with revenue to continue its war against Ukraine.

The senators—Republicans Susan Collins, Lisa Murkowski, Thom Tillis, and John Curtis, and Democrats Jeanne Shaheen, Richard Blumenthal, and Ron Wyden—called on the administration to reverse course, saying the US should not provide Russian President Vladimir Putin with “a financial lifeline.”

What the 2022 law requires before the ban can end

The law, signed on 8 April 2022, allows the president to end the import ban only after submitting a certification to Congress. The certification must find that Russia has agreed to pull out its forces and stop the fighting on terms Ukraine's free and independent government accepts, no longer poses an immediate threat of attack to any NATO member, and recognizes Ukrainians' right to pick their own government.

The law also requires consultation with four congressional committees and a report at least 45 days before certification. The termination takes effect 90 days after certification unless a joint resolution of disapproval is enacted into law during that period. The senators allege the administration failed to meet the consultation and reporting requirements. Their statement does not establish whether a certification has been submitted.

Treasury’s license cites sanctions rules, not the 2022 law

The Treasury Department's Office of Foreign Assets Control issued General License No. 135 on 9 October, authorizing certain transactions involving Russian-origin diesel that would otherwise be restricted under US sanctions regulations. It runs until 7 April 2027 and cites sanctions regulations, not the 2022 import-ban law.

Treasury Secretary Scott Bessent defended the deal on Fox News on 11 October, saying the administration would proceed under existing legal authority. He said lawmakers who argued that either the earlier law or the current Lindsey Graham sanctions law prohibited the deal were wrong, and argued the agreement would lower prices, Reuters reported.

How much diesel Trump says Russia will supply

Trump said on Truth Social that Russia would immediately supply more than 300,000 tons of diesel to US and global markets, followed by 500,000 tons in November and 1 million tons after that. He said Russia would deliver another 3 million tons “within a short period of time,” depending on the condition of its diesel refineries. The promised volumes have not been independently verified.

Russia partially lifted its diesel export ban on 10 October, allowing 500,000 tons onto the global market at this stage, the Russian government said, according to state news agency TASS.

A House bill to block Russian oil purchases

Pennsylvania Republican Rep. Brian Fitzpatrick plans to introduce the Ronald Reagan Peace Through Strength Act to block Russian oil purchases and use a discharge petition to force a House vote, Axios reported. The procedure can force consideration of a bill if 218 House members sign. Republican Rep. Don Bacon said he would support the bill and called Trump's decision a serious mistake, according to Ukrainska Pravda.

Barrasso defends the deal. Zelenskyy calls it an investment in war

On CBS's Face the Nation on 11 October, Senate Majority Whip John Barrasso, a Republican from Wyoming, called the deal “another point of leverage” for Trump to use against Putin. Asked whether the decision violated US law, Barrasso said the president was balancing competing priorities and had to make tough decisions.

Ukrainian President Volodymyr Zelenskyy wrote on Telegram on 9 October:

“Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged.”

Trump also expects Ukraine to stop striking Russian refineries under his proposed energy ceasefire, a White House official told Axios. Zelenskyy said Kyiv would halt such strikes if Moscow did the same.
