Telecommunications giant Qwest refused to provide the government with access to telephone records of its 15 million customers after deciding the request violated privacy law, a lawyer for a former company executive said Friday. For a second day, the former National Security Agency director defended the spy agency’s activities.

In a written statement, the attorney for former Qwest CEO Joseph Nacchio said the government approached the company in the fall of 2001 seeking access to the phone records of Qwest customers, with neither a warrant nor approval from a special court established to handle surveillance matters.
