Watch: Ex-Trump aide defying Mueller gets cross-examined on live TV

In a historic interview, former Trump aide Sam Nunberg tells Ari Melber he won’t comply with Mueller’s Grand Jury Subpoena because the Russia probe is trying to "set up” his mentor Roger Stone. For the first time, Nunberg admits on live TV That Mueller offered him “immunity”, but he claims he’s willing to go to jail and defy the Special Counsel.
