Sarah Huckabee Sanders: ‘I can’t guarantee’ Trump never said N-word on tape

President Trump on Tuesday escalated his attacks on Omarosa Manigault Newman, the former White House aide who is on a tour promoting her new memoir. Newman says in the book that she heard a tape from the set of “The Apprentice” in which Trump used the N-word. White House press secretary Sarah Huckabee Sanders told reporters Tuesday that she “can’t guarantee” that Trump did not use the slur on a recording. Meanwhile, Trump lashed out again on Twitter, calling Newman a “dog.” NBC’s Kristen Welker reports for TODAY.
