[Trump's ally Graham pushes to put pressure on Russia] U.S. Senator Lindsey Graham, a close ally of U.S. President Donald Trump, is pushing forward a plan to impose new sanctions on Russia and impose high tariffs on countries that buy Russian oil, gas and uranium. At the same time, Trump is working to fulfill his campaign promise to end the Russia-Ukraine conflict. On Wednesday, the South Carolina Republican said in an interview that the number of people supporting his bill has exceeded the key threshold of 60, meaning it has enough votes to overcome the Senate's obstruction. Graham expects that by the end of the week, the bill will have the support of at least 67 co-sponsors, enough to override a potential presidential veto.
