U.S. President Donald Trump’s initiative to lower diesel prices by easing sanctions on Russia has faced criticism from Republican Senator Thom Tillis. During an interview on NBC's Meet the Press, Tillis raised concerns about the legality of Trump's decision to temporarily relax sanctions on Russian diesel, suggesting it could violate congressional law. "I do believe there’s a legitimate case for saying the president’s not following the law," Tillis stated.
Tillis's remarks reflect unease among some Republican lawmakers who support Ukraine amid its ongoing conflict with Russia, which began in February 2022 following Russia's invasion. He indicated that his support for Trump’s legislative priorities would depend on the administration reversing its course on the sanctions relief. "If the president wants my support, which I believe he should get for funding military operations and year-end funding beyond baseline funding, I think the president needs to understand this is a problem, and I’m not the only Republican concerned with this," Tillis added.
Tillis has emerged as a critical voice within the Republican Party, expressing concerns over what he perceives as overreach by the Trump administration. His term as a senator is set to conclude in January 2026, as he announced he would not seek re-election after facing a primary challenge from Trump in North Carolina.
On the same day, Tillis joined a bipartisan group of senators in a letter opposing the sanctions relief for Russia. The group included Republicans such as Susan Collins, Lisa Murkowski, and John Curtis, along with Democrats Jeanne Shaheen and Richard Blumenthal. They stated, "The United States should not provide [Russian President Vladimir] Putin with a financial lifeline while Russia continues to kill Ukrainian civilians. The Administration must immediately reverse course."
Representative Don Bacon, another retiring Republican, also criticized the sanctions relief, asserting that supporting Putin's economy is morally wrong. This dissent highlights divisions within the Republican Party regarding the U.S. response to Russia’s invasion of Ukraine.
Trump has previously criticized Ukrainian President Volodymyr Zelenskyy, suggesting that a change in leadership could facilitate a ceasefire. He stated, "I suggest they get a new leader who can make a deal, because he could have made many deals, and for some reason, he never does."
On October 10, Trump announced an agreement with Putin to supply 300,000 tonnes of diesel to the global market, with an additional 500,000 tonnes expected in November. U.S. Treasury Secretary Scott Bessent defended the administration's decision to ease some sanctions, stating it was necessary to address rising diesel prices.
Analysts have expressed skepticism about the long-term impact of this decision on fuel prices, with critics like Tillis referencing existing laws that prohibit the importation of Russian fuel, including a 2022 executive order. A recent law, named after the late Senator Lindsey Graham, also prohibits U.S. investment in the Russian energy sector.
The rise in global fuel prices this year has been largely attributed to the U.S.-Israel conflict with Iran, which began in February and has restricted commercial traffic through the Strait of Hormuz, a vital route for fuel trade. Tillis emphasized the need to address the situation in Iran and hold Putin accountable for the energy crisis. "It’s Vladimir Putin who owns the responsibility for energy prices to the extent that they come from that part of the world," he said.
Trump's decision has also drawn international criticism, with Canadian Prime Minister Mark Carney's office expressing support for Ukraine. In a statement, Carney's office noted, "This agreement is in direct opposition to the efforts of Ukraine, Canada, and our allies to create peace and stability in Europe. It will provide additional revenue for Russia and help finance its illegal, unjustifiable war against Ukraine."
