Donald Trump has asked the Senate to delay voting on a bipartisan Russia sanctions bill, Republican Senator Roger Wicker said on June 4.

“I know that he (Trump) asked the leader (Senate Majority Leader John Thune) not to bring the bill to a vote this week,” Wicker said during a meeting of the Defense Writers Group in Washington.

The bill, introduced on April 1 by Senators Lindsey Graham ® and Richard Blumenthal (D), seeks to impose a 500% tariff on imports from countries that continue purchasing Russian oil and raw materials.

Its aim is to tighten economic pressure on Russia and discourage third-party nations from enabling the Kremlin’s energy exports.
