CNBC revealed on Wednesday that the Mueller team has been asking witnesses to hand over their personal phones and provide investigators access to their encrypted messaging programs such as WhatsApp, Confide, Signal and Dust as part of their investigation into whether the Trump campaign colluded with Russian operatives.
In an interview with CNBC on Thursday, Giuliani said he wouldn't agree to provide the president's personal devices unless certain preconditions were met beforehand.
"I wouldn't do it now. I wouldn't reject it out right either. I would ask for preconditions to be met. I would want to know why they need it," Giuliani said. "They would have to ask for specific conversations off of that phone because they are going to be listening to things they shouldn't be listening to. I'm talking about protecting his legal rights and confidential presidential conversations," he added.
