Lok Janshakti Party (LJP) chief Chirag Paswan said on Tuesday that Bihar CM Nitish Kumar is anxious that he will be sent jail if LJP comes in power in this assembly elections and that's why his party (JDU) is releasing videos. "Do I have to prove now how sad I am on my father's [Ram Vilas Paswan] demise?" Chirag Paswan said.
