SEN. GRAHAM: So Rudy Giuliani last night said he's got the goods on Hunter Biden. I called the attorney general this morning and Richard Burr, the chairman of the Intel Committee, and they told me take very cautiously anything coming out of the Ukraine against anybody...But if Rudy Giuliani has any information coming out of the Ukraine, he needs to turn over the Department of Justice because it could be Russian propaganda.

MARGARET BRENNAN: You last time you're on this program now in December, you said Giuliani should come to the Judiciary Committee with what he said was a suitcase full of documents he picked up in Ukraine on the Bidens. Are you saying you don't want any part of this anymore?

SEN. GRAHAM: After talking to the attorney general and the intelligence chairman that any documents coming out of the Ukraine against any American, Republican or Democrat, need to be looked at by the intelligence services, who has expertise I don't because Russia is playing us all like a fiddle.

MARGARET BRENNAN: Can you clarify? You said you talked to Attorney General Barr--

SEN. GRAHAM: This morning.

MARGARET BRENNAN: --this morning. Has the Department of Justice been ordered to investigate the Bidens?

SEN. GRAHAM: No. The Department of Justice is receiving information coming out of the Ukraine from Rudy--

MARGARET BRENNAN: Already?

SEN. GRAHAM: --to see. He told me that they've created a process that Rudy could give information and they would see if it's verified. Rudy Giuliani is a well known man. He's a crime fighter. He's loyal to the president. He's a good lawyer. But what I'm trying to say- to the president and anybody else, that the Russians are still up to it. Deterrence is not working. So let's look at Hunter Biden's conflict. Let's look at Joe Biden. Vice President Biden, what did you do when they told you your son was on Burisma's board? It undercuts your ability to fight corruption. Did you take it seriously? Obviously he didn't. But when it comes to documents coming out of the Ukraine, to Republicans and Democrats, be very cautious turning--

MARGARET BRENNAN: But- I understand that. However, when you're talking about being asked to do these things in a channel being open between Rudy Giuliani and the Justice Department, this sounds a lot like this is in some ways a taxpayer funded oppo-research operation against Joe Biden. Isn't this exactly what was at the heart of the impeachment probe to begin with?

SEN. GRAHAM: No, not at all.

MARGARET BRENNAN: Who's paying Rudy Giuliani?

SEN. GRAHAM: I don't know. Here's my message to Rudy: If you've got something coming from the Ukraine, turn it over to the intelligence people, the Department of Justice, to any Democrat.
