Rudy Giuliani said Thursday that former FBI director James Comey is the “biggest liar” of 2016 and 2017.

“Our position is simple: We will cooperate, as we have already with 1.2 million documents, if they convince us they are objective and can accept the truth,” Giuliani said on Fox Business Network. “They think the truth here is defined by James Comey, James Comey is the biggest liar of 2016-2017.”

Giuliani also said former Deputy FBI director Andrew McCabe and Comey were both pointing fingers at each other for lying, but he believes they are both liars.

“McCabe is a big liar, Comey even bigger,” Giuliani said.
