Addressing comments by Sen. Lindsay Graham (R-S.C.) that he’d arranged for Giuliani to present Justice officials with fruits of his on-the-ground research into the Bidens and Ukraine, Barr said information originating in Ukraine must be treated with caution.

“The Department of Justice has the obligation to have an open door to anybody who wishes to provide us information that they think is relevant,” Barr said in response to a reporter’s question at a news conference on unrelated database hacking charges. “I did say to Sen. Graham, we have to be very careful with respect to any information coming from the Ukraine.”…

“There are a lot of agendas in the Ukraine. There are a lot of cross currents and we can’t take anything we receive from the Ukraine at face value,” Barr said. He said the department’s stance on accounts or evidence emerging from the former Soviet republic is a broad one, but he emphasized it would apply to “any information Giuliani might provide.”
