Senator Rand Paul was the sole Republican to vote against advancing legislation aimed at imposing stricter sanctions on Russia, with the bill also including expanded measures against Iran. The bill proposes increasing duties on goods imported from the Russian Federation to up to 500 percent ad valorem.

This legislation would grant the president authority to place tariffs of up to 100% on the top five purchasers of Russian oil and natural gas, among other potential penalties. The bill's language states that "not later than 30 days after the date of the enactment of this Act, the President shall, notwithstanding any other provision of law, increase the rate of duty for all goods, including oil, natural gas, liquefied natural gas, petroleum, petroleum products, petrochemical products, coal, and coal products, imported into the United States from the Russian Federation to a rate of up to 500 percent ad valorem.”

Senator Lindsey Graham, who died before the bill's advancement, had previously announced his intention to seek White House approval for a revised text that included these provisions. Following Graham's passing and amid renewed tensions with Iran, Senator Paul stated on July 19 that "Republicans should add Iran to the Russian Sanctions Bill. That’s what Lindsey wanted to do, and it was going to happen.”

Paul, however, referred to the legislation as the "latest counterproductive attempt to hold Russia accountable for its war against Ukraine." His vote against advancing the bill highlights a division among Republicans regarding the approach to international sanctions and foreign policy.
