LARRY KING has revealed that he sometimes 'doesnt know why he made the decision to leave primetime television. At the end of an interview with Russian Prime Minister Vladimir Putin on his CNN talkshow, Putin requested whether he could ask a question himself. I dont know why? But the King leaves the scene at the US stage? Putin said. King interjected: I sometimes dont know why myself. As Putin complemented King on his profile and his abilities, and again questioned why the veteran presenter would stand down from his position, King replied: Thank you, thank you. I have no answer. King is due to step down from his talkshow in January, to be replaced by Piers Morgan. DS
