Marco Rubio doesn't need convincing Vladimir Putin kills his opponents ... he says it's obvious.
We got the Senator from Florida in D.C. Tuesday to get his take on Putin straight-up getting asked by FOX News host Chris Wallace why so many of his political rivals end up dead.
You'll recall Putin answered by calling out the U.S. for the assassinations of JFK and MLK. Rubio ain't buying the answer because there's a fundamental difference in those murders.
Rubio also wants Prez Trump to get a reality check ... Putin's not America's friend!!
