Mr. Nunberg said that he was subpoenaed to go before a grand jury on Friday, but it is unclear from his bombastic interviews whether he has information that will prove valuable to Mr. Mueller, or whether he is a campaign aide simply nursing old wounds in a manner created to grab a cable-obsessed president's attention.
The grand jury is one of two summoned by special counsel Robert Mueller in his investigation of whether President Trump or his colleagues engaged in any criminal activity prior to or during the presidential campaign, or during his presidency.
Nunberg told Tur he would not co-operate with Mueller, saying: "It's a witch hunt and I'm not going to cooperate".
It was not immediately clear what consequences Nunberg might face for his refusal to appear before a grand jury.
Mr Nunberg also suggested he thinks the special counsel's team believes they have something on Mr Trump. He waved his subpoena around in front of MSNBC's Ari Melber on air. "I don't know why he does", Nunberg said. "I could be wrong, by the way".
The Times also reported Nader, who advises Emirates' Crown Prince Mohammad Zayed Al-Nahyan, attended a January 2017 meeting that Mueller's team has probed.
At the time, Nunberg's firing was viewed as part of a broader struggle between Trump aides Corey Lewandowski and Roger Stone. He relayed his impression that Mueller has something quite serious on Trump, which is not exactly a surprise, but someone from anywhere near his corner admitting it is new.
"I got carried away. I thought it would be amusing".
Last month, Mr. Nunberg agreed to be interviewed by Mr. Nunberg asked CNN's Jake Tapper. "Who the hell advised him to allow those Russians in the Oval Office?" Mr. Nunberg thought his involvement with the special prosecutor was over when he received a grand jury subpoena and then reacted in a most unlawyerly fashion. Wiley said in the broadcast she was "flabbergasted" at what she was hearing.
"It is not an easy thing to do", McDougal said. "The difference is, I didn't know anything". After the Seychelles meeting, Nader visited the White House several times, and met at least once there with Bannon and Kushner, these people said. Aides in the West Wing voiced frustration that Nunberg had thrust Russian Federation back into the headlines while also laughing at what they considered his lack of discipline.
Sanders also played down Nunberg's importance. "Let him arrest me", Nunberg declared to The Washington Post on Monday. OK, fine, yeah, she's unattractive. "She's not attractive. She's a fat slob". "Crazy people. Nunberg's workshopping his insanity defense and if it works for him, it will work for the whole administration!"
Even separate from that question, though, it was clear Nunberg was under plenty of pressure. That's where the story actually goes from here. Most recently, former Trump campaign aide Rick Gates pleaded guilty to making false statements and conspiring against the United States.
When Nunberg said the subpoena was costing him 80 hours of time as he tried to sort through the documents and emails Mueller had requested, Wiley interjected, somewhat incredulously: "You'd rather spend possibly a year in jail than 80 hours going through documents?" He campaigned his a- off. "Talking to you, I have smelled alcohol on your breath", she said.
During Monday's interviews, Nunberg oscillated between saying Trump hadn't colluded and suggesting he might have had some arrangement with Russian Federation. "[Russian President Vladimir] Putin is too smart to collude with Donald Trump".
Colbert went on to quip about the extent of Nunberg's tirade.
Nunberg added that there would be "no more television" appearances but that he had "no regrets" about any of his TV hits on Monday. Minutes later, he called into CNN, where Gloria Borger interviewed him.
On Monday, Nunberg raised eyebrows again after appearing on CNN sounding drunk and unhinged.
Axios spoke with an unnamed friend of Nunberg's who accused news anchors of "knowingly taking advantage of an obviously fragile man". "I was just pointing out some of the errors in his thinking".
"Well, I haven't had a drink", he replied.
