DEA Phone Database Eclipses NSA Efforts

Working with AT&T to access phone data going back to 1987

For at least six years, law enforcement officials working on a counternarcotics program have had routine access, using subpoenas, to an enormous AT&T database that contains the records of decades of Americans' phone calls — parallel to but covering a far longer time than the National Security Agency's hotly disputed collection of phone call logs.

The Hemisphere Project, a partnership between federal and local drug officials and AT&T that has not previously been reported, involves an extremely close association between the government and the telecommunications giant.
