The U.S. House of Representatives is expected to take up legislation next week that would impose additional sanctions on Russia, following the Senate’s 86-11 approval of the measure in August. The legislation, formally known as the 'Lindsey O. Graham Sanctioning Russia and Iran Act of 2026', was championed by the late Sen. Lindsey Graham of South Carolina.

The Senate passed the bill on Aug. 7 after more than a year of negotiations. The legislation would strengthen sanctions targeting Russia and individuals and entities connected to its war effort while giving President Donald Trump additional authority to impose tariffs of up to 100% on major purchasers of Russian oil and natural gas. It also includes provisions extending the Iran Sanctions Act through 2031.

The bill was closely associated with Graham, who worked on the legislation before his death in July. His sister, Sen. Darline Graham Nordone, introduced the Senate measure after taking his seat, while Democratic Sen. Richard Blumenthal of Connecticut helped shepherd it through the Senate. The legislation was ultimately approved with support from lawmakers in both parties.

The package would also target Russia’s energy revenues by imposing penalties on countries that continue purchasing large amounts of Russian oil and natural gas. Supporters argue that reducing Moscow’s energy income would increase economic pressure on Russia and limit resources available to sustain its war in Ukraine.

The legislation has faced some concerns in the House, particularly over the extent of the tariff authority it would give the president. Some Democrats have questioned whether the measure grants the White House too much discretion to impose tariffs on countries that purchase Russian energy, while supporters argue the authority would provide additional leverage against Russia.

The House consideration will determine whether the Senate-passed legislation can advance toward the president. If the House approves the Senate version without changes, the bill could proceed to the White House for consideration. If lawmakers make changes, the legislation will require additional congressional action before it could reach the President.
