Political strategist Prashant Kishor on October 21 took a dig on Bihar Chief Minister Nitish Kumar. He alleged that Nitish Kumar has not closed all his channels with Bharatiya Janata Party in spite of joining the Mahagathbandhan a month ago.He said, “As far as I know, Nitish Kumar is surely with Mahagathbandhan but hasn't closed his channels with BJP, biggest proof is that RS Dy Chairman-JDU MP Harivansh neither resigned from his post nor party asked him to do so.”
