Weeks after the Andhra and West Bengal government hit out at the centre by banning the CBI from operating in their respective states, Finance Minsiter Arun Jaitley in an exclusive interview to NewsX has hit out at both Chandrababu Naidu and Mamata Banerjee for obstructing the investigation agency. He says that both Naidu and Mamata are the ones who are a threat to the federal structure of the country, and adds that both Chief Ministers are afraid of the skeletons in their closets. Stopping the CBI is their attempt to shield the corrupt ministers in their states says Jaitley.
