Lawmakers will wait as US President Donald Trump considers his own sanctions, John Thune has said

The US Senate has paused a bill from hawkish Senator Lindsey Graham that proposes imposing 500% secondary tariffs on Russia's trading partners, according to Senate Republican leader John Thune. Graham previously claimed the measure would give President Donald Trump a "sledgehammer" to use against Moscow to resolve the Ukraine conflict.

Speaking to reporters on Monday, Thune said he would pause progress on the sanctions package after Trump signaled he could take action independently. The legislation, co-authored by Democratic Senator Richard Blumenthal, aims to penalize countries that import oil, gas, uranium, and other goods from Russia.

"It sounds like right now the president is going to attempt to do some of this on his own," Thune said, as quoted by Politico. "If at some point the president concludes that it makes sense and adds value and leverage that he needs in those negotiations to move the bill, then we'll do it. We'll be ready to go."

Trump said on Monday that he was "very unhappy" with Russia and threatened tariffs of up to 100% on countries that continue trading with Moscow unless a deal to end the Ukraine conflict is reached within 50 days. He made the remarks during a meeting with NATO Secretary-General Mark Rutte in the Oval Office.

Trump also said the US will supply weapons to Ukraine through NATO, which will handle both payment and distribution.

Thune suggested Trump's plan could eliminate the need for Senate action on the Graham-Blumenthal bill. He added that lawmakers would coordinate with the White House and the House and that the legislation would remain "ready to go at a minute's notice," as quoted by the outlet.

When asked if the bill might be considered before the summer recess, Senate Majority Leader Steve Scalise responded, "Not right now."

Russian Deputy Foreign Minister Sergey Ryabkov said earlier this month that the "hypothetical arrival" of secondary tariffs on Russian trade partners would not alter Moscow's policy. Russia "will continue to move along our independent, sovereign, and sustained path," the diplomat stated.

Russian President Vladimir Putin has said sanctions are harming the West more than Russia. "The more sanctions are imposed, the greater the damage to the imposers," he stated last month.
