In 2002, Mark Klein, a former technician for AT&T, came forward with information that the company was collecting data for the National Security Agency. His testimony was central to several class-action lawsuits against AT&T for its alleged wiretapping.
Klein is now in Washington, D.C., to speak out against a possible Senate deal that would grant immunity to AT&T and the other telecoms for their role in NSA surveillance — effectively nullifying those lawsuits.
