The Kremlin said U.S. President Donald Trump signaled to Ukraine that it should continue the war after he said he would send more weapons to Kyiv and threatened Russia with secondary sanctions unless it makes peace.

Trump said the United States would put secondary tariffs on countries that do business with Russia if a peace deal is not reached in 50 days.

The legislation, which would allow the president to levy a 500% tariff on imports from countries that purchase Russian uranium, gas and oil, has gained momentum in the Senate as Trump has signaled he will escalate US action against Russia.
