Yahoo asks to reveal argument against NSA surveillance

Yahoo has asked a secret court to unseal its argument in a 2008 case protesting government surveillance. Those documents would prove that the company fought back against the National Security Agency's data gathering program, Yahoo said. Yahoo is the latest Internet giant to ask a Foreign Intelligence Surveillance Act Court for permission to reveal more information about their efforts to protect their users' privacy. Microsoft and Google have asked the court for permission to publish statistics about how infrequently they turn over user data to the government.
