"In 2006, USA Today published an article that revealed that Verizon, AT&T and BellSouth (since acquired by AT&T) were voluntarily providing the NSA with millions of call logs. It also said another landline provider, Qwest (since acquired by CenturyLink), refused to hand over logs without a warrant, and that the NSA had rejected Qwest's insistence that the matter go before the FISC.
In 2007, former Qwest CEO Joseph Nacchio was convicted on 19 counts of insider stock trading. During an appeal, Nacchio's lawyers claimed the charges were retaliation for Nacchio's refusal to go along with the warrantless surveillance program while he ran Qwest."
