His first inkling that something was amiss came in summer 2002 when he opened the door to admit a visitor from the National Security Agency to an office of AT&T in San Francisco.
"What the heck is the NSA doing here?" Mark Klein, a former AT&T technician, said he asked himself.
A year or so later, he stumbled upon documents that, he said, nearly caused him to fall out of his chair. The documents, he said, show that the NSA gained access to huge amounts of e-mail, Web search and other Internet records of more than a dozen global and regional telecom providers. AT&T allowed the agency to hook into its network at a facility in San Francisco and, according to Klein, many of the other telecom companies probably knew nothing about it.
Klein is in Washington this week to share his story in the hope that it will persuade lawmakers not to grant legal immunity to telecommunications firms that helped the government in its anti-terrorism efforts.
Klein, 62, said he may be the only person in the country in a position to discuss firsthand knowledge of an important aspect of the Bush administration's domestic surveillance. He is retired, so he isn't worried about losing his job. He carried no security clearance, and the documents in his possession were not classified, he said. He has no qualms about "turning in," as he put it, the company where he worked for 22 years, until he retired in 2004.
