Earlier, speaking to national news outlets, Nunberg said he had failed to comply with an order from Mueller to turn over emails with Trump's staff and that he would also refuse to show up to testify before a grand jury Friday despite being offered immunity.
As Trump flirted with running for president, particularly in 2011, there were only two main political aides for the NY real estate developer: Republican political hatchet man Roger Stone and his protege, Nunberg.
"Why do I have to do it?"
Nunberg told MSNBC's Katy Tur that he thinks the Federal Bureau of Investigation may have something on Trump - or maybe not. Nunberg was close to Bannon, but he has said a lot of very negative things about Trump. Although he said Trump "may have done something" illegal during the election, he also added: "I don't know that for sure".
Nunberg says that the request is too onerous for him.
French embassy attacked in Burkina Faso
In recent years, Al Qaeda in the Islamic Maghreb has pushed south from its base in Algeria, into Mali, and then to Burkina Faso. Burkina Faso, a landlocked nation in West Africa is one of the poorest countries in the world.
Trump fired Nunberg in August 2015 after racially offensive posts appeared on his Facebook page. "I think he may have done something during the election". Russian Federation has denied the allegations and Trump has said there was no collusion between Moscow and his campaign.
His change of heart comes after a series of freaky interviews in which he declared he'd sooner be arrestedthan appear before a grand jury this week. "Let him arrest me", he said of Mueller's operation.
"Donald Trump won this election on his own. As we've said many times before, there was no collusion with the Trump campaign", said White House press secretary Sarah Sanders when asked about his comment.
Nunberg also told Politico that if Trump had colluded with Russian Federation, it would be known by now because the president "can't keep his f-ing mouth shut".
For the casual follower of the news, it is understandable that it is hard to remember who Nunberg is and to distinguish him from other names in the news like Carter Page, Roger Stone, George Papadopoulos, or Rick Gates. He has said many times that the FBI's investigation into collusion with Russian Federation and the Trump campaign is a "witch hunt".
MSNBC's Willie Geist questioned whether others will be willing to accept the risk involved with working for the Trump administration. "But that's irrelevant. The person she works for has a 30% approval rating". "He said frightful things about Sarah Huckabee Sanders, says he wants to fight Corey Lewandowski in an alley ... he also had disgusting things to say about Carter Page".
