Secretary Scott Bessent said if the Supreme Court rules against the administration on tariffs, refunding the funds would be “terrible” for the Treasury.

Treasury Secretary Scott Bessent signaled on Sunday that the U.S. is open to partnering with European countries to impose more sanctions on countries that buy Russian oil in an attempt to “collapse” the Russian economy and brushed aside concerns that the U.S. was entering a recession.

“We are prepared to increase pressure on Russia, but we need our European partners to follow us,” Bessent told NBC News’ “Meet the Press.”

“We are in a race now between how long can the Ukrainian military hold up, versus how long can the Russian economy hold up?” Bessent added. “And if the U.S. and the [European Union] can come in, do more sanctions, secondary tariffs on the countries that buy Russian oil, the Russian economy will be in total collapse, and that will bring [Russian] President [Vladimir] Putin to the table.”

Last month, the Trump administration imposed 50% tariffs on India, some of the highest tariffs the U.S. has imposed on any foreign nation, citing the country’s continued purchases of Russian oil amid the war in Ukraine.

Bessent’s comments come just hours after Russia launched its largest air attack of the war overnight, killing at least four people and setting fire to a government building in Kyiv.

Also on Sunday, Ukrainian President Volodymyr Zelenskyy told ABC’s “This Week,” that putting tariffs on countries that continue making deals with Russia is the “right idea. He also said he thinks “President Trump is right” about his criticism of European countries that still buy Russian oil.

“I’m very thankful to all the partners, but some of them, I mean, they continue [to] buy oil and Russian gas and this is not fair,” Zelenskyy said.

“I think, what I think, I think the idea to put tariffs on the countries who continue make deals with Russia. I think this is right idea,” he added later.

The remarks also come just weeks after Trump flew to Alaska to meet with Putin for the first time in his second term. Days later, the American president hosted Zelenskyy and European leaders at the White House to discuss a potential end to the war.

Since then, it appears that talks of a ceasefire or an end to the war have stalled, and Russia has continued its onslaught of airstrikes on Ukraine.

Last week, NBC News reported that Trump has grown pessimistic about efforts to end the war, though he joined European leaders on phone calls where he urged them to join the U.S. in putting pressure on China for supporting Russia’s war effort.

Bessent also spoke about President Donald Trump’s economic agenda, dismissing concerns about tariffs and about last week’s August jobs report. The treasury secretary also dismissed concerns that it was a sign of a “jobs recession” in the U.S.

Bessent on Sunday also spoke about the Trump administration’s appeal to the Supreme Court seeking to overturn a circuit court decision that ruled against the president’s far-reaching tariffs.

“I am confident that we will win at the Supreme Court,” the treasury secretary told “Meet the Press” moderator Kristen Welker.

He added, however, that if the Supreme Court rules against Trump, “there are numerous other avenues that we can take” to continue to impose tariffs on foreign nations.

But those other avenues, Bessent added, would “diminish President Trump’s negotiating position.”

In a ruling signed by seven judges of the U.S. Court of Appeals for the Federal Circuit, the court said Trump had misused his authority when imposing tariffs on foreign nations under the guise of the president’s emergency powers. The court said that only Congress has the power to impose such sweeping tariffs.

Asked whether the Trump administration would be ready to issue refunds for the tariff revenue it has collected if the Supreme Court ruled against it, Bessent said, “We would have to.”

“We would have to give a refund on about half the tariffs, which would be terrible for the Treasury,” Bessent said, adding later: “If the court says it, we’d have to do it.”

Still, the treasury secretary largely defended Trump’s tariff agenda on Sunday, telling Welker earlier in the program that tariffs are not a tax on the American people and pointing to other markers of success in the economy.

“If things are so bad, why was the GDP 3.3%? Why is the stock market at a new high? Because, you know, with President Trump, we care both about big companies and small companies,” Bessent told Welker.
