Former Finance minister P. Chidambaram as also former Communications Minister Kapil Sibal has criticised the CAG for exposing the corruption in the 2G and Coal scams. At that time BJP was effectively utilising these exposures and used it for election campaign.
Now the new Finance Minister in the NDA government, Arun Jaitely also has started advising and threatening the CAG.
Those who are in power are really afraid of CAG and their reports.
