Microsoft is now going on the offensive and have asked the US Attorney General Eric Holder calling for more light to be shed on the Prism program, and how Microsoft has been assisting the NSA.

Microsoft warn in the that “the Constitution itself is suffering” over the controversy.

Microsoft has come under particular scrutiny with the news of it allowing the NSA to access Outlook, Skype and Hotmail. This coupled with the news of the Xbox One and Kinect 2.0 being able to record, has had people up in arms, concerned with their privacy.

Forbes report that the letter from Microsoft refers to both Holder’s and the president’s knowledge of the Constitution and argues that more light needs to be shed on the program.

“As I know you appreciate, the Constitution guarantees the fundamental freedom to engage in free expression unless silence is required by a narrowly tailored, compelling Government interest,” Microsoft wrote.

“It’s time to face some obvious facts. Numerous documents are now in the public domain. As a result, there is no longer a compelling Government interest in stopping those of us with knowledge from sharing more information.”
