Nitish Kumar today said there should be a special discussion on the Citizenship (Amendment) Act (CAA) in the Bihar assembly, becoming the first ally to openly call for a rethink on the controversial law and apparently modifying his stand after his party Janata Dal (United) supported the bill in parliament. The Chief Minister made the remarks after the Congress and Lalu Yadav's Rashtriya Janata Dal (RJD) attacked the religion-based citizenship law in the special session of the Bihar house.
