MD of Kalaignar TV. Both are currently in Tihar jail and applied for bail.
Kanimozhi and Kumar, named as accused in the second charge sheet for allegedly taking bribe of 200 crore rupees, were arrested on May 20 after the special court dismissed their bail pleas in the case.
The apex court also sought the status of Rs 200 crore allegedly given to Kalaignar TV.
Terming corruption as the worst form of human rights violation, the apex court asked the CBI to estimate loss accrued to the exchequer on account of licenses issued to telecom operators during the tenure of A Raja as Telecom minister.
A bench comprising justices B S Chauhan and Swatanter Kumar also asked the investigating agency to inform it about the status of trial in the 2G case before a CBI special court.
Both Kanimozhi and Kumar have 20 per cent stake each in Kalaignar TV Pvt Ltd, which allegedly received 200 crore through a “circuitous” route from Shahid Balwa promoted DB Realty.
The matter has been posted for further hearing on June 20.
