[NYTimes] C.I.A. Is Said to Pay AT&T for Call Data
"The C.I.A. is paying AT&T more than $10 million a year to assist with overseas counterterrorism investigations by exploiting the company’s vast database of phone records [...]. "
"AT&T has a history of working with the government. It helped facilitate the Bush administration’s warrantless surveillance program by allowing the N.S.A. to install secret equipment in its phone and Internet switching facilities, according to an account by a former AT&T technician made public in a lawsuit."
