Russian President Vladimir Putin has denied any Russian involvement in the downing of Malaysia Airlines Flight 17.
But Sen. John McCain says the evidence is clear, and the U.S. needs to hold him accountable.
"The point here is that Vladimir Putin it literally getting away with murder, and I mean literally. And we are doing very little in response," McCain said.
U.S. officials say evidence suggests Pro-Russian rebels fired a surface-to-air missile at the plane, killing nearly 300 people.
Russian leaders are placing the blame on Ukraine, claiming it was one of their own fighter jets that shot the plane down.
