Sen. Marco Rubio (R-FL) on Sunday warned that the U.S. cannot trust the Russian government to cooperate not that the country has invaded Crimea, Ukraine.
"We know that the Russians have basically violated every major treaty they’ve ever entered into. We’ve seen how they’ve basically lied. Let’s call it what it is. They are lying and this government is a government of liars, the Russian government," he said on NBC's "Meet the Press." "I think they’re increasingly behaving like an enemy of international peace and international norms."
Rubio added that Russia is a threat to American interests.
"And they are certainly, as it regards to that, an enemy of the United States with regard to those things I just outlined. And if you look at the positions they’ve taken, on issue after issue, Russia has been an obstacle to U.S. national interests," he said.
