According to several sources, slime-ball William Barr is warning trump that Giuliani is becoming a threat to the administration, but trump is ignoring the warnings.  You know what the mob usually does when one of their own becomes a liability, trump isn't listening, he loves the way Rudy goes around on Faux News and creates a scene.  trump just isn't ready to fit old Rudy with cement shoes yet, it's only a matter of time though, everyone who deals with trump eventually has to pay the price.
