Washington (CNN) Senate Majority Leader Mitch McConnell said Sunday he believes President-elect Donald Trump's hopes of working more cooperatively with Russia "will be dashed pretty quickly."

The Kentucky Republican's comments came in an interview on CBS's "Face the Nation," a day after Trump had tweeted: "Having a good relationship with Russia is a good thing, not a bad thing. Only 'stupid' people, or fools, would think that it is bad!"

McConnell said Trump's hopes are probably wishful thinking.

"I don't think it's all that unusual for a new president to want to get along with the Russians. I remember George W. Bush having the same hope," McConnell said.

"My suspicion is, these hopes will be dashed pretty quickly," he said. "The Russians are a big adversary, and they demonstrated it by trying to mess around in our election."
