Chris Christie says FBI raid on Roger Stone was "overkill"

Former New Jersey Gov. Chris Christie is revealing his 15-year friendship with Donald Trump in his new memoir. Called "Let Me Finish: Trump, the Kushners, Bannon, New Jersey, and the Power of In-Your-Face Politics," Christie writes that he went from the vice presidential short list to being fired from the transition team two days after the election. Christie, who claims Trump's son-in-law, Jared Kushner, pushed him out, joins "CBS This Morning" to discuss his new book and the pre-dawn FBI raid on former Trump adviser Roger Stone.
