Trump's decision to waive provisions of a Russia sanctions bill he had signed weeks earlier drew objections from a number of Republican members of Congress, some of whom argued the action could weaken diplomatic leverage over Moscow. Late on a Friday, Trump used an executive order to remove a package of sanctions and tariffs that had been designed to pressure Russia into bringing the war in Ukraine — which began in February 2022 — to a close.

Objections came from legislators across party lines and from Ukrainian President Volodymyr Zelensky, whereas a senior Russian official offered a welcoming response. Objections from two Republican members of Congress — North Carolina's Thom Tillis in the Senate and Nebraska's Don Bacon in the House — surfaced on social media over the administration's policy shift, with Tillis pointing to a Senate vote of 86-11 that had backed the underlying legislation and arguing that easing pressure on Moscow effectively accommodated a government conducting an active military campaign against Ukraine, while Bacon put forward the view that the change would prolong rather than end the conflict.

The statute at the centre of the dispute, bearing the name of the late South Carolina Republican senator Lindsey Graham, had been designed to tighten economic constraints on Russia by imposing restrictions on its officials, financial institutions, and the network of tankers used to transport its oil and gas exports throughout the ongoing war. Texas Republican Senator John Cornyn added his opposition by posting on X that Graham would have found the decision objectionable, while Oklahoma Governor Kevin Stitt had told a television outlet in a prior interview that the proposal carried a risk of drawing out the conflict in Ukraine without meaningfully reducing fuel costs.

The White House press secretary stated that a recently concluded diesel supply agreement was expected to increase global market availability and put downward pressure on fuel costs, with lowering prices for farmers, truckers, and families described as a priority alongside the administration's push for both parties in the Russia-Ukraine conflict to halt attacks on refinery infrastructure, which officials linked to rising consumer costs. Patrick Casale, a senior adviser to Nevada Republican Party chairman Michael McDonald, described the diesel agreement as one element within a broader set of measures aimed at reducing fuel prices while the administration also pursues an end to the war, though Casale separately expressed the view that certain members of the Republican Party were working against the president's interests.

The signing of the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 into law on September 18 was accompanied by a statement expressing hope that the measure might draw both parties in the conflict toward the negotiating table to bring the fighting to a close. The order signed Friday suspends enforcement of multiple sanctions provisions and additional tariffs that the Graham Act authorises, with the accompanying text stating that the president had notified Congress of a determination that granting the suspension serves the country's national interests.

Separately, the underlying statute allows for a 500 percent tariff on goods arriving from Russia — with certain statutory carve-outs — along with potential 100 percent tariffs on goods from the five largest buyers of Russian-origin crude oil and natural gas, contingent on those buyers making new purchases on or after October 18. Under the measure, a full 100-percent tariff rate would apply to imports from whichever five countries are identified as the top enablers of efforts to circumvent restrictions on Russian oil. Under the waiver, those additional duties — scheduled to take effect on Sunday — remain suspended for as long as the exemption holds.

Speaking at the United Nations General Assembly on September 22, Trump indicated that the U.S. was coordinating closely with Russian and Ukrainian leadership toward a resolution of the conflict, and he expressed a desire to bring the fighting to a close, noting that the war between the two nations had been taking a considerable toll in lives each month. He pointed to his recent signing of the sanctions legislation, noting that it extends broad new tariff powers to the presidency — authority he indicated he stood prepared to deploy if circumstances required. He called for an end to the violence.

Zelensky took to X on Saturday to voice opposition to what he described as a decision by the United States to set aside the Lindsey Graham Act — legislation he said had been designed to place effective pressure on Russia toward ending the conflict — with his post noting that the move came as Russian forces had just carried out strikes on more than 15 Ukrainian power facilities, which he characterised as among the largest such attacks on the country's energy infrastructure. Overnight artillery fire claimed at least four lives, including that of an ambulance driver, while dozens of others were treated for wounds.

Kirill Dmitriev, who serves as an envoy to Putin, described the suspension of certain provisions of the Graham Act as an event of genuine historical weight in a written statement responding to Trump's decision. That waiver has deepened the friction between Washington and Kyiv, with the two sides at odds over how the administration has handled relations with Moscow — notably through moves to expand energy output while pushing for lower fuel costs.

Senate Minority Leader Chuck Schumer, a New York Democrat, characterized the sanctions relief as a gift to Russia's president timed to his birthday, while Senator Richard Blumenthal of Connecticut — who helped draft the underlying legislation — argued that the waivers serve Moscow's interests rather than those of U.S. allies or the majority of Congress. Separately, Trump, in remarks to reporters at the time the earlier diesel supply agreement was announced, described the arrangement as meeting a global need for fuel.

Lawmakers from across the ideological spectrum have questioned whether easing restrictions on Russian energy sales would direct additional revenue toward Moscow while its forces continue operations in Ukraine. Tillis was one of roughly a dozen senators who put their names to a formal request that month, urging Trump to step back from the agreement — a move that placed him at odds with his own party's position.

In a letter addressed to the president, the lawmakers contended that the arrangement would generate additional revenue for Russia to sustain its military operations in Ukraine, with the legislators stating that permitting Moscow unrestricted access to global diesel markets would undermine national security interests and amount to an abandonment of Ukraine, whose population has continued to resist an ongoing armed conflict they describe as unlawful. In an October 13 letter, the senators argued that the agreement amounted to a concession to an opposing power while undermining the interests of allied nations, and called for it to be reversed.

Neither the executive order nor any documented evidence draws a direct connection between the diesel agreement and the wider sanctions waivers.
