Trump personal attorney Rudy Giuliani slammedGiuliani: Avenatti a 'Pimp' Michael Avenatti on Friday, calling the lawyer for adult-film star Stormy Daniels a "pimp."

"I don't get involved with pimps," Giuliani told Business Insider in an interview. "The media loves to give him room because he makes these roundabout charges and they turn out to mean nothing. He's going to get himself in serious trouble."

Avenatti challenged Giuliani to a televised debate on Tuesday.

He responded to the former New York City mayor's attack later Friday, posting a video from 2000 featuring Giuliani dressed in drag and performing a skit with Donald Trump at the Inner Circle Press Roast in Manhattan.

Avenatti this week disclosed financial records of President Trump's personal lawyer Michael Cohen showing that he had obtained $1.2 million from four major corporations through a shell company he set up to pay $130,000 to keep Daniels from discussing an alleged affair she had with Trump in 2006.

The companies — AT&T, Novartis, Korea Aerospace Industries, and Columbus Nova, an investment firm with Russian ties — have confirmed the payments to Cohen.

Avenatti's report, which included errors seized upon by Cohen's attorneys, was based on his bank records. The Treasury Department's inspector general is investigating how Avenatti obtained the information.

In April, the FBI seized boxes of information from Cohen's office, home and hotel room in a raid. Agents were armed with search warrants based in part on information obtained by Russia special counsel Robert Mueller's investigators.

"I think he's got a lot of explaining to do," Giuliani told Business Insider, adding that he did not know how Avenatti came upon Cohen's data.

"I wouldn't debate him because it wouldn't be fair.

"I debate, like, really intelligent, skilled people," Giuliani, pointing to Harvard law professor emeritus Alan Dershowitz.

"I know Alan Dershowitz," he said. "He's no Alan Dershowitz."
