Sprint, the country's third-largest wireless provider, was the only cellphone company to receive "the secret legal basis of a then-classified program that collected Americans’ phone records by the billions for counterterrorism purposes" because it was the only company to demand access to that legal rationale before the program was revealed last year by Edward Snowden's leaks, the Washington Post reports. After receiving the rationale, Sprint continued to turn over phone call records to the NSA, the Post also reports.
