"It's obvious that the Russians hacked into our campaigns," McCain said in a Reuters interview Monday. 

"But there is no information that they were intending to affect the outcome of the election, and that's why we need a congressional investigation."

McCain made similar comments on CBS's "Face The Nation" Sunday. 

"Whether they intended to interfere to the degree that they were trying to elect a certain candidate, I think that's a subject for investigation," McCain said.

"But the facts are stubborn things. They did hack into this campaign," he said
