Sen. Rand Paul (R-Ky.) slammed Sen. Lindsey Graham’s (R-S.C.) push for Russian sanctions, calling his bill “self-defeating economic warfare.”

Graham’s sanctions bill on Russia would impose a 500 percent tariff on imports from any country that buys Russian oil, gas, uranium and other products. The legislation has more than 80 co-sponsors in the Senate, potentially making it veto-proof. 

But GOP senators are waiting on President Trump to move ahead with the legislation, and Trump said this week he hasn’t even looked at it. Trump has also said he doesn’t want to undermine the chances of a peace deal between Russia and Ukraine.

Paul, in a series of posts on X on Saturday, said the bill would be ineffective and backfire against efforts to achieve peace, as the war between Russia and Ukraine continues in its fourth year.

“The Graham bill would derail President Trump’s efforts to negotiate an end to the war in Ukraine. Self-defeating economic warfare is no way to achieve peace,” Paul said on X.

“This bill won’t force China or India to change behavior, but it will impose an effective embargo on ourselves that will hurt American families,” he said.

Paul also argued that the bill could hurt U.S. allies and raise gas prices.

“The Graham bill could raise tariffs on allies like Israel and Taiwan to 500 percent and potentially even higher. Why are we punishing our friends while pretending it’ll hold Russia accountable? This isn’t strategy—it’s economic self-sabotage,” he wrote.

“Cutting off Russian oil takes a major source of supply off the market, resulting in higher gas prices. Analysts warned that a U.S. ban on Russian oil could cause prices to hit $160–$200 a barrel. That’s $5+ gas at the pump,” he said.

Graham, this past week, sought to address some of those concerns by proposing a carveout for his bill to exempt countries that aid in Ukraine’s defense.

The carveout could help insulate countries in Europe that still import Russian gas and have provided military support for Ukraine, as well as other U.S. partners that have straddled the line between maintaining ties with Moscow and providing assistance to Kyiv. 

“A lot of countries still buy Russian oil and gas but less. Some European countries still have relationships with Russia, but they’ve been very helpful to Ukraine. So I want to carve them out,” Graham told reporters Wednesday.

“I tell China, if you don’t want to have a 500 percent tariff, help Ukraine.”
