News reports in December 2005 first revealed that the National Security Agency (NSA) has been intercepting Americans’ phone calls and Internet communications. Those news reports, combined with a USA Today story in May 2006 and the statements of several members of Congress, revealed that the NSA is also receiving wholesale copies of American's telephone and other communications records. All of these surveillance activities are in violation of the privacy safeguards established by Congress and the US Constitution.

In early 2006, EFF obtained whistleblower evidence from former AT&T technician Mark Klein showing that AT&T is cooperating with the illegal surveillance. The undisputed documents show that AT&T installed a fiberoptic splitter at its facility at 611 Folsom Street in San Francisco that makes copies of all emails web browsing and other Internet traffic to and from AT&T customers and provides those copies to the NSA. This copying includes both domestic and international Internet activities of AT&T customers. As one expert observed, “this isn’t a wiretap, it’s a country-tap.”

Secret government documents, published by the media in 2013, confirm the NSA obtains full copies of everything that is carried along major domestic fiber optic cable networks. In June 2013, the media, led by the Guardian and Washington Post started publishing a series of articles, along with full government documents, that have confirmed much of what was reported in 2005 and 2006 and then some. The reports showed-and the government later admitted—that the government is mass collecting phone metadata of all US customers under the guise of the Patriot Act. Moreover, the media reports confirm that the government is collecting and analyzing the content of communications of foreigners talking to persons inside the United States, as well as collecting much more, without a probable cause warrant.
