As the FISA court approves limits to the NSAs phone-record tracking, anonymous sources tell The Wall Street Journal that the agency actually collects 20 percent or less of American call records, contradicting reports that the program creates a comprehensive database. NSA head Keith Alexander has said that the agency is not currently collecting any location information under the program, but in 2010 and 2011, it gathered cellphone location data as part of a test project. According to them, however, this is the result of a steep decline: in 2006, the NSA was reportedly collecting nearly all records from a number of US companies, but the number had dropped to 30 percent by the summer of 2013, when the programs existence was first leaked.
