WASHINGTON (Reuters) - The National Security Agency and the FBI are tapping directly into the central servers of nine leading U.S. Internet companies, allowing investigators to examine e-mails, photos and other documents that can be used to track people and their contacts over time, The Washington Post reported on Thursday.
The highly classified anti-terrorism program, code-named PRISM, had not been disclosed publicly before. A U.S. government source who was not authorized to comment publicly on the program confirmed its existence to Reuters late Thursday.
