In an unprompted phone call, Rudy Giuliani vented his frustrations after Michael Cohen’s sentencing to Yahoo News in a colorful tirade.

“Our strategy is … to do everything we can to try to convince Mueller to wrap the damn thing up, and if he’s got anything, show us,” Giuliani told Yahoo News. “If he doesn’t have anything, you know, write your report, tell us what you have, and we’ll deal with it. He can’t prosecute [Trump]. All he can do is write a report about him, so write the goddamned thing and get it over with now.”

Giuliani then turned his lasers to the just-sentenced Cohen, who will serve three years in prison for crimes including lying to Congress and tax evasion.

“Cohen is a completely dishonorable person. … I’ve never heard of a lawyer that tape-recorded their client without the client’s permission, and I’ve known some pretty scummy lawyers,” Giuliani said. “You don’t exist very long in the legal profession if you go around taping your client.”

Giuliani also stuck to Trump’s party line that Cohen’s crimes were not related to the President or his campaign.

“The President’s not a lawyer,” Giuliani said. “The simple fact is that it’s not a criminal violation of the campaign finance law.”

“How do they all of a sudden become campaign finance prosecutors? You need a special prosecutor for campaign finance? I mean, they started with collusion. … After two years and two investigations … they have nothing on collusion,” Giuliani continued. “Then, they started squeaking about obstruction. They’ve got nothing on obstruction, and Article II prevents them from doing anything about obstruction. Now they’re doing campaign finance.”

He also added his professional opinion that collusion is “like the biggest bunch of bullshit.”
