NORAH O’DONNELL: Let me ask you about what Chairman Nunes has done. Do you think it was appropriate that he went to go view these so-called intelligence reports on White House grounds?

SENATOR JOHN MCCAIN: Well, I think there needs to be a lot of explaining to do. I’ve been around for quite a while and I’ve never heard of any such thing. And– obviously– in a committee like an intelligence committee, you’ve got to have bipartisanship, otherwise the committee loses– credibility.

And so– l– there’s so much out there that needs to be explained by the chairman. And– look– if– this is a very serious issue. It all started with Russian interference– attempt to change the outcome of our election. And so, it’s turning into a centipede like these things have a tendency of doing. And another shoe seems to drop every few days.

NORAH O’DONNELL: And I know that’s why you have called for a select committee, an independent committee, because of the seriousness of these allegations. Should Chairman Nunes reveal his source?

SENATOR JOHN MCCAIN: Well, absolutely. I can’t imagine why not. And I also believe that the entire committee should be engaged. The reason why the armed services committee– honestly does, is successful is we work in a bipartisan fashion. Senator Burr and Senator Warner on our intelligence committee are in the Senate, work closely together. They may have differences, but– you’ve got to have a bipartisan approach to an issue such as this if you want to be credible. . . .

There is more engagement– with– with false information. There is– a lot more associated with Russian attempts to affect America. Our election, but there’s also a lot of other Russian activities going on. For example, right now, they’re attempting to affect the outcome in France.
