The Bill fundamentally challenges the idea of India.”Senior Congress leader Kapil Sibal, in reply to Home Minister Amit Shah’s statement that no Muslim needs to worry over Citizenship Amendment Bill, 2019, said that no Indian Muslim is scared of the current regime. “You made a very objectionable statement earlier. Which Muslim fears you? No Indian Muslim fears from you. Neither I nor any other citizen of the country is scared of you. We fear only from the Constitution of the country,” he said.
