Published reports say AT&T was the National Security Agency s primary telecommunications partner and facilitated much of its surveillance efforts around telephone and Internet traffic collection. The NSA, according to the documents, has surveillance equipment installed at least 17 AT-T Internet hubs in the U.S., far more than in Verizon hubs, the reports say. The documents show that NSA agents display a cordial, friendly nature given that the agency’s relationship was not contractual. The papers also spell out a timeline of post-September 11 data mining and sharing.
