ANDERSON COOPER (HOST): I want to pick up on a conversation that Senator Santorum and Carl Bernstein were having before the break, questioning why people in the Trump orbit continue to lie about Russia. I mean, does it -- is there an explanation for you in this? On just the number of lies related to Russia, senator?

RICK SANTORUM: Well, I guess the point I was trying to make to Carl is the -- the president doesn't tell the truth about a lot of things fairly consistently, and so, the fact that he's not telling the truth about Russia fairly consistently, at least in the eyes of people around here, why is that any different?

I mean, it's -- it's not like he's doing something out of character with the Russia investigation that he's not doing in any other areas.

So, that -- that's -- so, you make the point, “oh, he lies about Russia all the time.” Well, according to what I hear on this -- this roundtable and the network, he lies about everything all of the time, so, what's the difference?

JEFFREY TOOBIN: Is that really -- is that really the best defense you can come up with? The fact that, “well, he lies about everything.”
