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.

The EU adopted its largest-ever round of sanctions listings on 12 October, targeting the suppliers behind Russia’s war industry, the Council of the EU announced. The bloc acted as Russia keeps killing Ukrainian civilians every day, while US President Donald Trump eases sanctions on Russian diesel.

Russia’s planned winter campaign against Ukraine’s infrastructure depends on arms factories fed by a web of component suppliers and on oil revenue that still flows despite Ukraine’s refinery strikes, so every supplier cut off from that web raises the cost of waging it. As Washington eases off, Europe’s own pressure has a gap: its ports still take record volumes of Russian Arctic gas, and a full ban on long-term contracts starts only in 2027.

Missile suppliers top the list

More than half of the new listings hit the supply chain for ballistic missiles that Russia “uses to kill Ukrainian civilians every day,” EU foreign policy chief Kaja Kallas said in the statement. Russian attacks killed more than 150 people in the past week, Ukrainian President Volodymyr Zelenskyy said on 11 October.

The list names 826 Russian companies, mid-level firms the Council calls the “core” of Russia’s arms industry, with at least €20 billion in yearly turnover, and 743 people who run them. They make parts for missiles, drones, and military aircraft, from semiconductors and radars to explosives and navigation systems. Their assets are frozen, EU firms may not finance them, and the executives may not enter the EU.

Foreign ministers ratified a deal EU envoys reached on 7 October. Ukraine’s sanctions commissioner Vladyslav Vlasiuk said 60% of the listings came from Ukrainian proposals.

Ministers reject the diesel deal

EU foreign ministers in Luxembourg vowed to keep the sanctions despite Trump’s diesel deal with Russian President Vladimir Putin, Euronews reported. Kallas addressed Washington directly as she arrived.

“The US is our biggest ally, but our message is clear: if we want to end this war, the only way we can do this is (by) putting more pressure on Russia,” Kallas said.

Irish Foreign Minister Helen McEntee called the deal “concerning,” and Lithuanian Foreign Minister Kęstutis Budrys said it was “not the European way.” Kallas warned that an energy truce covering only refineries would favor Russia, since Ukraine has one refinery and Russia “plenty.”

Trump announced the diesel deal on 9 October, and the US Treasury waived sanctions on Russian diesel until April 2027. Zelenskyy said the EU would provide about €3 billion more in military aid this week.

Washington presses Kyiv

Trump expects Ukraine to stop hitting 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. On 10 October, Trump told reporters it was time for Ukraine to get a new president. Germany’s foreign minister, Britain’s defense secretary, and a senior lawmaker from Chancellor Friedrich Merz’s party backed Zelenskyy, while the Kremlin sided with Trump.

Zelenskyy offered to hold elections after a 60-day ceasefire, and Kallas said elections are impossible while the war goes on. The Institute for the Study of War assessed that Russia exploits Ukraine’s legal ban on wartime elections to drag out the war.
