Nunberg appeared before a grand jury as part of Special Counsel Robert Mueller's probe. That claim would contradict repeated denials by the president and what the president's son and son-in-law said under oath.
CNN cited anonymous sources saying Cohen was willing to share that information with special counsel Robert Mueller, who is investigating possible collusion between Trump's campaign and Russian Federation.
Trump, who in the past has denied knowing about the meeting before it happened, also shot back at Cohen, who was once so loyal to Trump that he said he'd take a bullet for his boss.
"I wish these guys could put down their arms, recognize the longevity of their relationship and stop the backbiting and the infighting", Scaramucci said.
As recently as a few weeks ago, however, Giuliani said, "I do not expect that Michael Cohen is going to lie", during an interview with CNN's Dana Bash in response to a question about whether he thought Cohen will flip.
Earlier this month, Nunberg was reportedly pitching himself for television appearances with the description of "Michael Cohen's Friend".
"I didn't know him very well".
"And, frankly, by the time anyone was aware of it, which was summer of this year, as I stated earlier, I wouldn't have wanted to get him involved in it because it had nothing to do with him", Trump Jr. added. The Justice Department has been investigating Cohen for months, raiding his home, office and hotel room in search of documents related to a $130,000 payment the attorney facilitated before the 2016 election to Stormy Daniels, an adult-film actress who says she had sex with Trump in 2006.
The New York State Bar Association calls such secret recording unethical.
CBS News' Elections and Survey's Director Anthony Salvanto reports that this speaks to how Trump's strongest backers feel such a personal connection with the president and want to defend him against what they perceive as being a politically motivated witch hunt. So Cohen's actions were not illegal. But he called the former Trump attorney's recording of a private conversation with the president "highly suspect".
Chris Wallace is dismissing the notion that the latest news about Michael Cohen will be of any real political or legal danger to President Donald Trump. The president insinuated Cohen might be making up stories in order to cut a deal after the Federal Bureau of Investigation raided his home and office and seized financial records of Cohen's taxi medallion business.
Nunberg worked for years with both Trump and Cohen and briefly served on the Trump campaign, but was sacked in August 2015.
