A Key member pf President Trump's legal team, Rudy Giuliani said Saturday that somebody "played around" with the tape released by the President former personal lawyer Michael Cohen.

Giuliani rejected Cohen's recent reported claim that Trump knew in advance of a meeting between top campaign officials and a Russian lawyer offering dirt on Hillary Clinton ahead of the 2016 election.

Trump on Friday vehemently repeated his denial that he knew about the meeting, which is at the center of Mueller's probe, tweeting "NO", he "did NOT know of the meeting with my son, Don jr".

"I think, largely speaking, Trump supporters are going to look at this and say, 'Oh, it's Michael Cohen covering for himself, he has the Clinton apparatus around him, '" Costello said.

On Sunday, Giuliani argued that the recordings about Mr. Trump "clearly corroborate" the president's position that he was not aware ahead of time about payments to McDougal or Stormy Daniels, the adult film actress who received $150,000 from a company set up by Cohen in exchange for her silence about an alleged affair.

CNN cited anonymous sources saying Cohen was willing to share his information with Mueller, who is investigating possible collusion between Trump's campaign and Russian Federation.

During an interview on "Fox News Sunday", Giuliani called Cohen a "scoundrel" and a "liar". Raddatz asked Abrams and Chris Christie, a former U.S. prosecutor and New Jersey governor who is an ABC News contributor, for their thoughts on the Trump team's legal strategy in regard to Cohen. Trump tweeted Friday Cohen was just "trying to make up stories" to distract from his own troubles.

Giuliani said he was working on getting the original tape, adding: "We have determined the fact that he tampered with the tape in the sense he abruptly mid-conversation turned it off".

Trump and his attorneys have said that the recordings had been cut down to make it seem as if the president acted improperly. Giuliani has claimed Trump told Cohen, "Don't pay with cash", suggesting he wanted the payment to be properly documented.

"There are 12 others - maybe 11 or 12 others - out of the 183 in which the president is discussed at any length by Cohen, mostly with reporters", Giuliani said. "Obviously, if I knew that I never would have said he was a reputable lawyer, I'd have said he was a scoundrel".

Earlier this month, Nunberg was reportedly pitching himself for television appearances with the description of "Michael Cohen's Friend".
