Legal analyst Alan Dershowitz sparred with Michael Avenatti, the attorney representing Stormy Daniels, on CNN Friday over whether and when Avenatti had conversations with Michael Cohen, President TrumpDonald John TrumpThe Hill's Campaign Report: Democratic field begins to shrink ahead of critical stretch To ward off recession, Trump should keep his mouth and smartphone shut Trump: 'Who is our bigger enemy,' Fed chief or Chinese leader?

In a CNN segment, Dershowitz questioned how Avenatti could speak with Cohen without first consulting Cohen's counsel after reports that Avenatti told Cohen the two men should work together against Trump during a chance dinner encounter last week.

"He did, according to press reports, have a conversation with Mr. Cohen at a restaurant, and that raises some questions, because you know you're not supposed to speak to somebody who's counseled, as a lawyer, and ask him whether you want to get together and hurt Trump," Dershowitz said.

"I don't know if that occurred, but if it did occur, [I think] Michael has to do some explaining," he added.

Avenatti responded, rebuking Dershowitz for speaking about conversations Avenatti said Dershowitz had no knowledge about.

"Alan, you really need to start talking only about things that you know about as opposed to things you have no knowledge about," Avenatti said. "You have no knowledge of the communications that went on between me and Michael Cohen's representatives ... long before that restaurant meeting."

Cohen's attorneys reportedly also raised ethical concerns about Avenatti’s reported chance meeting in court this week, according to ABC News.

Avenatti pressed on in the CNN debate, referencing Dershowitz's claim that he had been uninvited from dinner parties in Martha's Vineyard over his stance on the special counsel investigation.

"You just make it up as you go along," Avenatti added. "You need to go back and concentrate on what invites you get at Martha's Vineyard, since that appears to be what you are really good at."

Avenatti previously told MSNBC that he would be interested in representing Cohen against Trump if he were willing, and has reportedly urged Cohen to turn on the president.

"If he was prepared to do the right thing, come clean, and basically turn state's evidence, I would absolutely consider it," Avenatti said last week. "Michael Cohen and I actually had the chance to converse."
