New Delhi, Jan 20 (TIWN) Upping the ante against the government over journalist Arnab Goswami's purported social media chat leak, the Congress on Wednesday described it as an act of "treason" and demanded an immediate inquiry over leaking of such classified information about the Balakot air strikes.

The Congress also said it will raise the issue of the alleged chat leaks in Parliament's Budget session.  The Congress brought out several senior members of the party to corner the government over the issue with former Defence Minister A.K. Antony, former Home Minister Sushil Kumar Shinde, former Law Minister Salman Khurshid and party spokesperson Pawan Khera.  Addressing a press conference here at the party headquarters, Antony said, "The contents of the leaked chats between Goswami of Republic TV and the former CEO of BARC is a serious issue for the entire nation."  Antony said that for a very patriotic Indian, it is a shock and a serious matter of concern because it affects national security.
