"You're not in a position where you could possibly know that properly", Dershowitz told Avenatti during an appearance on ABC's This Week.
Avenatti added: "Number two, this shows that the president knew these payments were being made prior to the election".
On the same day that the recordings were given to prosecutors, The New York Times reported that Cohen recorded himself and President Trump discussing a potential payment to former Playboy model Karen McDougal, who claimed she had an affair with Trump in 2006. It's very possible that there could be multiple recordings of Cohen speaking to Donald Trump or other individuals.
Porn actress Stormy Daniels' lawyer Michael Avenatti says "there's multiple tapes" of Donald Trump talking to his lawyer Michael Cohen. "And ultimately, I think he is going to cooperate with us as it relates for our search for the truth".
Trump said it was "inconceivable that a lawyer would tape a client - totally unheard of and perhaps illegal". In February, a White House spokesperson told ABC News, "This is an old story that is just more fake news". He also claimed that nothing in the tape shows that Trump "had any knowledge of it in advance".
28th GST Council meeting in Delhi
If the sanitary napkins are technically under GST, but taxed at 0%, manufacturers will still be able to get input tax credits. In its meeting in November previous year, the Council had reduced rates in over 178 items in the 28 per cent tax bracket.
This is not the first time that Avenatti has suggested that there could be multiple recordings of conversations Trump and Cohen have had, but his claim has yet to be substantiated.
Avenatti declined to reveal any details, maintaining that the only way he would have acted improperly would have been if he received the tape from someone in law enforcement.
"I have a question for Michael Avenatti", Dershowitz said.
"All of the information that the Federal Bureau of Investigation seized, that's not under lock and key", he said. There's a host of other ways I could have obtained that information. "I could have received it from Michael Cohen; I could have received it from Michael Cohen's counsel; I could have received it from others".
In a statement, Cohen's attorney, Brent Blakely, said that neither he nor his client had cooperated with or provided any information to Avenatti. Avenatti, meanwhile, fired back at Cohen and his attorneys Sunday evening, tweeting that Cohen is "refusing" release recordings and documents.
