Bush's Law by Eric Lichtblau recalls much of the information from the Mark Klein declaration. Lichtblau writes: AT&T technician Mark Klein “answered the door of his office complex...to find an NSA representative who was there on an undisclosed mission. Not long after Klein learned of a secret room being built on the sixth floor of another AT&T facility on Folsom Street” in San Francisco. “Then he heard from other AT&T technicians about similar mystery rooms in other cities across the country. As Klein pieced together all the strange things he’d seen, the first thing he thought about was George Orwell’s 1984.”
