The National Security Agency—which possesses only limited legal authority to spy on U.S. citizens—has built that covers more Americans’ Internet communications than officials have publicly disclosed, current and former officials say.
The system has the capacity to reach roughly 75% of all U.S. Internet traffic in the hunt for foreign intelligence, including a wide array of communications by foreigners and Americans. In some cases, it retains the written content of emails sent between citizens within the U.S. and also filters domestic phone calls made with Internet technology, these people say.

The programs, code-named Blarney, Fairview, Oakstar, Lithium and Stormbrew, among others, filter and gather information at major telecommunications companies. Blarney, for instance, was established with AT&TInc., T +0.24% former officials say. AT&T declined to comment.
