The Senate will bring forward legislation that would sanction Russia’s trading partners, Sen. Lindsey Graham (R-S.C.) said Monday, pushing a bill placing added pressure on Russia to end its war with Ukraine.

President Donald Trump told reporters Sunday night that the proposed Senate legislation would be “OK with me,” his strongest approval on the sanctions. In a post on X, Graham — a key supporter of the bill — said “with President Trump’s blessing,” the Senate would move on the sanctions to “continue the momentum to end this war honorably, justly and once and for all.”

“This legislation is designed to give President Trump more flexibility and power to push Putin to the peace table by going after both Putin and countries like Iran that support him,” Graham wrote. “I appreciate the strong bipartisan support for this legislation in both the House of Representatives and the Senate.”

Senators had been reluctant to act on the bill without expressed support from the president, with the legislation remaining on hold for several weeksas Trump met with Russian President Vladimir Putin. But the president’s backing now paves the way for Congress to vote on the resolution, which has more than 80 Senate cosponsors.

The legislation would allow Trump to place secondary sanctions on countries like China and India who buy oil and gas from Russia, aiming to cut off the cash flow Russia rakes in from its energy exports — which largely funds its war in Ukraine. In his remarks to reporters Sunday, Trump also indicated he’d consider adding Iran to the list of countries on the chopping block.

“As you know, I suggested it, so any country that does business with Russia will be very severely sanctioned,” Trump said. “They may add Iran to that,” he added.

The added sanctions would place another layer of pressure on Russia to end the war in Ukraine. Last month, Trump placed new sanctions on two of Russia’s largest oil companies — Rosneft and Lukoil — after he said his talks with Putin weren’t taking steps toward peace.
