New Delhi, April 18 : Former Janata Dal leader and election strategist Prashant Kishor on Saturday slammed Bihar Chief Minister Nitish Kumar for what he called preaching on the lockdown but not raising the issue of state's migrant workers stuck in other states. "Across the country, people from Bihar are stranded and Nitish Kumar is giving lessons on the nationwide lockdown. Local governments are at least doing something, but Nitish Kumar has not spoken to authorities in any of the states. He did not even raise the issue during a meeting with Prime Minister Narendra Modi." Kishor's remarks came a day after Nitish Kumar, who is also Janata Dal-United President, maintained that the Uttar Pradesh government's move to send buses to Rajasthan's Kota to bring back stranded students was an "injustice" to the lockdown. The Uttar Pradesh government has sent scores of buses from Agra and Jhansi to Kota, which is a hub for institutes preparing students for various competitive examinations. /IANS
