Bihar Chief Minister Nitish Kumar today defended ally Lalu Prasad Yadav and his family after the Central Bureau of Investigation filed a chargesheet in the alleged job scam during Mr Yadav's tenure as Railway Minister in the Congress-led UPA government over 10 years ago. He said, "there's nothing in the case" and suggested the BJP is going after the Rashtriya Janata Dal patriarch only because their parties have joined forces against them.
