Nunberg said he plans to testify before a grand jury on Friday as scheduled and will hand over "as quickly as possible" email communications with the president and nine other Trump associates that Mueller demanded.
Nunberg told Bloomberg most of the communications he turned over to Mueller are from Stone and former White House chief strategist Steve Bannon, and that none of the documents were from Page, Hicks, or former campaign manager Corey Lewandowski.
"Why do I have to do it?" The subpoena indicates that Mueller may be focused not just on what Trump campaign aides knew and when they knew it, but also on what Trump himself knew. Both committees reportedly asked about the Trump Tower Moscow deal that never was.
Shortly after Nunberg lobbed the first allegation, White House press secretary Sarah Huckabee Sanders rebuffed him during the White House press briefing. I understand she was just doing her job, and I think she does a very good job under rough circumstances.
Trump has repeatedly denied any collusion. "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".
Nunberg became a prototype of sorts for a certain type of aide Mr. Trump attracted - unfailingly devoted, politically on the fringe and potentially volatile - he may prove to be an unpredictable witness for the same reasons the president's anxiety over the investigation continues to grow.
Nunberg, in a phone call to MSNBC, said a subpoena to appear before a grand jury was "absolutely ridiculous". "That Carter Page is a weird dude".
Nunberg acknowledged to Bloomberg that he had strategized how to reverse damage to his reputation from his phoned-in cable news appearances. And he blamed Trump for the investigation into Russian Federation meddling, telling MSNBC that he was "responsible for this investigation. because he was so stupid". He's been questioned "numerous times" by the special counsel's team.
Mueller also has been investigating whether the president has attempted to obstruct the probe, including whether he fired former FBI Director James Comey to undermine it. He then said he would reject a sweeping demand from Mueller for communications between him and top Trump advisers.
"I'm not holding anything back....[Complying with the subpoena] was much easier to do than I initially thought", Nunberg said. "I think it would be really, really amusing if they wanted to arrest me because I don't want to spend 80 hours going over emails I had with Steve Bannon and Roger Stone", he said, referring to both the former White House chief strategist and one of Trump's associates.
