'Okay if he leaves JDU': Nitish Kumar's huge statement on Prashant Kishor

Bihar CM Nitish Kumar has given a huge statement on Prashant Kishor. He said that Prashant Kishor should be asked if he still wished to stay as a part of Janata Dal United or not. The question has been tossed as Kishor has been working for Aam Aadmi Party in Delhi. 
Kumar revealed it was Amit Shah who suggested Prashant Kishor's name for JDU in the first place.  It seems that Nitish Kumar is evading from taking an action against Kishor himself
