Congress vice-president Rahul Gandhi is understood to have told party leaders not to criticise JD(U) president Nitish Kumar, PTI reported. It added that Kumar reciprocated by hinting that he would go along with the Opposition in the vice-presidential elections. Kumar recently broke ranks with the Opposition, saying he would support the BJP's candidate -- Ram Nath Kovind -- for President. Congress leader Ghulam Nabi Azad had attacked Kumar at the time, saying he wanted to ensure "Bihar ki beti" Meira Kumar's defeat. Meira is the Opposition's candidate for President. Kumar is chief minister of Bihar. PTI added that reports said Rahul had hinted that action would be taken against anyone criticising Nitish.
