Congressman PC Chacko is under attack for absolving the Prime Minister and Finance minister P Chidambram of any role in the telecom scam. As head of a parliamentary committee that studied the swindle, Mr Chacko has been accused by the opposition of engineering "a Congress document" that saves his own leaders and indicts former Telecom Minister A Raja for twisting a first-come-first-serve policy to help ineligible companies land sweetheart deals for mobile network licenses and second-generation or 2G airwaves.
