The National Security Agency (NSA) is using a program called "XKeyscore" that allows NSA employees, with no FISA warrant, to read databases containing emails, online chats and browsing histories of millions of Americans.
When Edward Snowden first released these NSA documents to The Guardian, weeks ago, he stated: "I, sitting at my desk could wiretap anyone, from you or your accountant, to a federal judge or even the president, if I had a personal email."
At the time, Rep. Mike Rogers (R-Ala.), GOP chairman of the House intelligence committee, claimed: "[Snowden] is lying. It's impossible for him to do what he was saying he could do."
However, it appears that Rep. Rogers was the one who was lying or unaware of the NSA's capabilities.
Training materials for XKeyscore explain how NSA employees can mine databases by completing a short on-screen form that is not reviewed by the FISA court or any NSA supervising personnel, reports The Guardian.
The XKeyscore training materials claim the program covers "nearly everything a typical user does on the Internet."
Under the Patriot Act signed by President Bush in 2001, the NSA is required to obtain a FISA warrant if they are targeting an "U.S. person," but XKeyscore allows NSA users to snoop U.S. residents without a warrant.
Ironically, the NSA released three heavily-edited documents today in an effort to claim "transparency." The information on the redacted documents, to be presented to the Senate judiciary committee, has already been released by Snowden.
