Rudy Giuliani says “no one really respects” ex-FBI director James Comey “or wants to hear from him.”

The late-night put-down came Friday after Comey bashed Attorney General William Barr, tweeting that the AG is “sliming his own Department.”

“If there are bad facts, show us,” Comey’s tweet continued. “An AG must act like the leader of the Department of Justice, an organization based on truth. Donald Trump has enough spokespeople.”

Giuliani, one of Trump’s personal lawyers, made his retort about an hour later.

“Someone should tell Jim Comey no one really respects him or wants to hear from him,” the former New York City mayor tweeted. “The Dems wanted him fired when he violated DOJ ethics in sliming Hillary. Rs believe he committed perjury and abused his power as FBI Director.”

Barr on Friday vowed to uncover the origins of the investigation of the Trump campaign. He previously characterized the investigation of Trump staff as “spying.”
