The newsman said that a single meeting with a Russian lawyer, President Trump's son-in-law Jared Kushner, then-campaign-chairman Paul Manafort, and other staffers is a far cry from collusion.
Giuliani said his shift stemmed from the revelation that Cohen had been "surreptitiously recording his clients" - referring to the tape of Cohen and Trump discussing a payment to former Playboy model Karen McDougal, who's alleged she had a long-running affair with Trump before he became president.
"I did NOT know of the meeting with my son, Don jr.", Trump tweeted Friday.
"I knew as soon as Giuliani spoke that he was damaging Trump's case immeasurably", Goldberg told CNN's "Erin Burnett Out Front".More news: Whyte makes his point against Parker at the O2 Arena

Trump's tweet about Cohen followed two others in which the president slammed special counsel Robert Mueller and his investigation in Russian meddling in the 2016 election. CNN first reported the news Thursday night. And the transcript makes it quite clear in the end that President Trump says 'don't pay with cash'.
The Justice Department, as part of its investigation into Cohen, is working to determine if he was involved in paying off women making claims about Trump, and whether that violated any campaign finance laws.
"These are tapes I want you to read", Giuliani said on CBS's "Face the Nation" Sunday.
Earlier this month, Nunberg was reportedly pitching himself for television appearances with the description of "Michael Cohen's Friend".
"I wish these guys could put down their arms, recognize the longevity of their relationship and stop the backbiting and the infighting", Scaramucci said. The Trump Org CFO also set up a monthly retainer through the company that was used to reimburse Cohen for the $130,000 hush money payment to Stormy Daniels. This contradicts his earlier statement that called Cohen an "honest, honorable lawyer". "He expressly waived attorney-client privilege last week and repeatedly and inaccurately - as proven by the tape - talked and talked about the recording, forfeiting all confidentiality".
Trump, who stands accused of pliancy towards Russian President Vladimir Putin, insists no president has been as "tough" on Russia and denies any collusion between his campaign and Moscow.
