The controversy surrounding 2G scam just refuses to die down, the latest being a letter accessed by NDTV that shows Murli Manohar Joshi, the Chairman of the Public Accounts Committee that is studying the 2G scam, having called the office of the Comptroller and Auditor General (CAG) before the latter placed its report on the scandal. As questions arise over whether Mr Joshi tried to influence the CAG report, is the probe into telecom scam getting delayed?
