"Show moral courage. No new promises please. Outline a credible action plan to deliver on the promises you have made to the people till date," he said in a series of tweets. The Chief Minister asked the Prime Minister to live up to his 2014 election promise of decriminalization and not announce tickets to candidates with criminal background.

Kumar further exhorted the Prime Minister to deliver on his promise to provide special status to Bihar and refrain from 'misleading' the people by way of special package to Bihar that PM Modi had announced at an official function in Arrah on August 18 last.

"Don't mislead with the so-called package where 86 percent is repackaged old schemes," the senior JD(U) leader said. On the Prime Minister's remark that something was wrong with the Chief Minister's DNA, Kumar asked the Prime Minister to 'take back the derogatory words'.

"Show moral courage. Take back your derogatory words on questioning the DNA and calling the state Bimaru and people as durbhagyashali (unfortunate)," the Chief Minister said and implored PM Modi to respect the sentiments of the people of Bihar who, he said, were "troubled by his unkept promises and unsavoury comments".

Kumar further asked the Prime Minister to stop indulging in rhetoric, chest thumping and making new promises one after another and 'accept his inadequacy to deliver on his old promises'.
