NBC’s Dateline will gather together 27 women who have accused Bill Cosby of sexual assault for one on-air interview special called “The Cosby Accusers Speak” on Friday. Correspondant Kate Snow will conduct the hour-long group interview of almost half of the women who have claimed to be assaulted by the comedian, including model Beverly Johnson, Eden Tirl and Lisa-Lotte Lublin, according to a promo for the special.
