In an unusual related legal development, on October 13, 2007, The Washington Post reported that Joseph P. Nacchio, the former CEO of Qwest Communications, is appealing an April 2007 conviction on 19 counts of insider trading by alleging that the government withdrew opportunities for contracts worth hundreds of millions of dollars after Qwest refused to participate in an unidentified National Security Agency program that the company thought might be illegal. According to court documents unsealed in Denver in early October as part of Nacchio’s appeal, the NSA approached Qwest about participating in a warrantless surveillance program more than six months before the Sept. 11, 2001 attacks which have been cited by the government as the main impetus for its efforts. Nacchio is using the allegation to try to show why his stock sale should not have been considered improper. [15] According to a lawsuit filed against other telecommunications companies for violating customer privacy, AT&T began preparing facilities for the NSA to monitor “phone call information and Internet traffic” seven months before 9/11.[16] (Source)
