Former Trump aide Sam Nunberg refusing to comply with Mueller subpoena


Sam Nunberg, a former aide to President Trump, has been subpoenaed by Robert Mueller’s special counsel. However, Nunberg says he refuses to cooperate, citing he sees no reason to spend hours digging up emails of his from 2015 that are requested. He talks to Katy Tur over the phone about the development in Mueller’s case, saying, "Trump may have done something during the election. I don't know what it is."
