Why Robert Mueller's testimony will be "all about the questions"
CBS News has learned Mueller composed an opening statement for the hearing regarding his 488-page report on Russia’s 2016 election interference that has not been reviewed by the Justice Department. The hearing will be Mueller’s 89th appearance before Congress. As in past appearances, he’ll likely bring a no-nonsense and cautious approach to the questioning. Paula Reid joins "CBS This Morning" to discuss what to expect.
