US Sen. Lindsey Graham said Sunday that a "turning point" in the war between Russia and Ukraine is approaching as NATO's Secretary General prepares to meet with President Donald Trump in Washington. Graham said he expects weapons to flow to Ukraine at a "record level" in the coming days during an appearance on CBS News.

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.

A bipartisan U.S. bill that would hit Russia with sanctions in a bid to pressure Moscow into good-faith peace negotiations with Ukraine has gained momentum this week in Congress, but it still lacks the presidential push it needs to get over the finish line.
