Two leading members of the House Judiciary Committee sent a letter to FBI Director James Comey regarding Stingray surveillance devices, which intercept cellphone communications. Representative Jim Sensenbrenner (R-Wisc) and Representative Sheila Jackson Lee (D-Tx) sharply criticized the FBI's use of "non disclosure agreements" that prohibit local law enforcement agencies from discussing the use of Stingrays, even in court proceedings. The representatives noted that such secrecy "shields the technology from debate." They asked the FBI to answer specific questions about the agreements. In 2013, EPIC first uncovered these secret Stingray agreements in a Freedom of Information Act suit against the FBI.
