But weirdly, he also seemed to say he thinks Mueller has something else on President Donald Trump.
White House spokeswoman Sarah Sanders dismissed Nunberg's comments.
"They want me in there for grand jury on Friday".
It's tough to believe that Mueller would be able to make much of Nunberg, regardless of his antics on Monday.
"He hasn't worked at the White House, so I certainly can't speak to him or the lack of knowledge that he clearly has".
"He's too smart for that, he didn't want it", said Nunberg of the president.

On Monday, Nunberg made headlines after telling the Washington Post that he would not comply with a subpoena springing from the probe into potential collusion between the Russian government and the Trump campaign. I think it would be amusing if they arrested me.

Whatever the reason, two outcomes are certain, according to New York Times political reporter Maggie Haberman: "aggravate Mueller and infuriate Trump". The subpoenas demand communications starting from November 2015, but Trump fired Nunberg in July 2015.
Nunberg rejected any notion that Trump had colluded with Russians, reports Reuters.
After spending hours on television Monday, Nunberg ended the phone interview after just three minutes, saying he needed to return to the arduous task of organizing the emails the special counsel asked him to provide via a written subpoena.
Nunberg said Trump's longtime aide Keith Schiller told him that Trump declined an offer from Emin Agalarov to send women to Trump's hotel room at the Moscow event. He said they acted professionally and that he was "very impressed by them" but that "what I'm not doing is following up with them".
Nunberg was sacked from the Trump campaign in 2015 and went on to endorse Sen.
