The Secret Relationship Between NSA and GCHQ

Bamford: I used the material and at the same time, I actually did have a somewhat of a relationship with NSA. He says he'd go up there maybe once every month or so and meet with my contact to ask for more information about what they were doing. Bamford was told by officials that if he didn't give it back his copy would be released under the Free Information Act. "I made one extra copy that I sent to somebody outside the country secretly"
