In his interview on CBS’ “Face the Nation”, Republican Senator Lindsey Graham, the chairman of the Senate Judiciary Committee, said the Department of Justice has “created a process that Rudy [Giuliani] could give information” collected in Ukraine to be verified.
Lindsey then warned, “... 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.”
Senator Graham has also reinstated that it was Russia and not Ukraine that interfered in the 2016 US presidential election and hacked the DNC, yet assuming Ukraine wasn’t involved “would not withstand scrutiny”.
Regarding Rudy Giuliani’s efforts to gather evidence in support of the president, the Senator said, “...they've [Justice Department] 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 anything over you got over to the intel community.”
