Bihar opposition leader Tejashwi Yadav came down heavily on Chief Minister Nitish Kumar on Friday for his much-assailed "gag order" to rein in criticism on social media, calling him the "Bhishma Pitamah" - the legendary father figure from the Mahabharata - of corruption. In a series of tweets, the Rashtriya Janata Dal (RJD) leader launched an all-out attack on Mr Kumar for the order by Bihar's Economic Offences wing asking all state departments to report any "defamatory, wrong" posts against ministers, MPs, MLAs, or officials. "The perpetrator of 60 scams, Nitish Kumar, the Bhishma Pitamaha of corruption, the protector of criminals, the weak chief of an immoral and unconstitutional government. Bihar police sell liquor. I challenge the Chief Minister to arrest me under this order," Mr Yadav wrote in Hindi.
