"Sure. Not a doubt in my mind," McCain, R-Ariz., responded when asked by the Washington Examiner.
McCain said the timing of the releases of information stolen from the NSA is proof that Snowden was colluding with the Russian government.
"Our real problem is Mr. Snowden is working for Russia, and he will be releasing information at appropriate times where it has the most significant impact damaging to the United States.
"I know that Mr. Putin is hospitable, but he usually wants somebody to pay the rent," McCain added.
