In a letter to Federal Communications Commission Chairwoman Mignon Clyburn, EPIC urged the FCC to determine whether Verizon violated the Communications Act when it released consumer call detail information to the National Security Agency. In response to an unprecedented Foreign Intelligence Surveillance Court order which focused on solely domestic communications, Verizon released telephone customer information to the NSA, including telephone numbers and time and call duration. Congress explicitly charged the Commission with investigating unauthorized disclosures of consumer call detail information. EPIC's letter stated that Verizon violated legal protections for consumer phone records when it disclosed consumer information in response to a facially invalid order.
