Brad Heath, USA TODAY | 07 April 2015 | The U.S. government started keeping secret records of Americans’ international telephone calls nearly a decade before the Sept. 11 terrorist attacks, harvesting billions of calls in a program that provided a blueprint for the far broader National Security Agency surveillance that followed. For more than two decades, the Justice Department and the Drug Enforcement Administration amassed logs of virtually all telephone calls from the USA to as many as 116 countries...current and former officials involved with the operation said. The data collection began in 1992 during the administration of President George H.W. Bush, nine years before his son, President [sic] George W. Bush, authorized the NSA to gather its own logs of Americans’ phone calls in 2001. It was approved by top Justice Department officials in four presidential administrations and detailed in occasional briefings to members of Congress but otherwise had little independent oversight, according to officials involved with running it.
