>> There was absolutely no collusion.>> The investigation into possible collusion between Donald Trump's presidential campaign and Russia taking a bizarre turn on Monday, with multiple cable news channels gripped by the rantings of an obscure former Trump aide. Saying he's refused to comply with a subpoena to testify before a grand jury and Special Counsel Robert Mueller's investigation.
>> Why are you saying no?>> Because what they sent me was absolutely ridiculous. They wanted every email I had with Roger Stone and with Steve Bannon.>> Sam nunberg, a protege of long time political strategist Roger Stone, started working for then businessman Trump in 2011, making him one of his earliest political advisors.
But he was fired from Trump's presidential campaign in August of 2015 before the 2016 election got fully underway. Nunberg said he was not concerned about being held in contempt for disregarding the subpoena, but he did say that the special counsel's suspicions of Trump may not be unfounded.>> Do you think that they have something on the President?
>> I think they may. I think that he may have done something during the election, but I don't know that.>> Mueller has indicted several Trump associates and more than a dozen Russian nationals. Last year, Stone was among Trump associates including former business partner Paul Manafort, whose communications and financial transactions were being investigated.
Last week, Manafort pleaded not guilty to a new indictment brought against him in Mueller's Russia probe, and will face trial in September.
