Extending further, Prime Minister Narendra Modi’s recent jibe on Bihar Chief Minister Nitish Kumar’s political DNA, Raghubar Das has now claimed to have examined of the Congress’ one.Addressing media persons on Friday, the Chief Minister criticised the Congress for stalling Parliament and robbing the country of development. “Congress has always pained this country, being in power or in the Opposition. It started with the Emergency and continued till recently with massive corruption. They are reduced to 44 and not even capable of getting Opposition’s tag. But hooliganism is in their DNA which ate up the entire Session,” said Das.
