Wyden Reveals Which Phone Companies Protect Privacy by Telling Customers About Government Surveillance
Wyden Inquiry Also Finds Wireless Carriers Did Not Follow Through on Requirement to Notify Senate of Surveillance Demands
Washington, D.C. – U.S. Senator Ron Wyden, D-Ore., today revealed which wireless carriers protect the privacy of their customers by notifying them about government surveillance requests for their information, in a letter he sent to his colleagues today. He urged senators to choose a phone company that will notify them about government surveillance requests.
“If law enforcement officials, whether at the federal, state, or even local level, can secretly obtain Senators' location data or call histories, our ability to perform our constitutional duties is severely threatened,” Wyden wrote. “This kind of unchecked surveillance can chill critical oversight activities, undermine confidential communications essential for legislative deliberations, and ultimately erode the legislative branch's co-equal status.”
Wyden referenced a 2024 report by the Department of Justice (DOJ) Inspector General, which revealed that during the first Trump Administration, the DOJ secretly obtained the phone records of several members of Congress and dozens of congressional staff, both Republican and Democrats, as part of a leak investigation.
Wyden learned that the largest phone companies — Verizon, AT&T, and T-Mobile — failed to establish systems to notify senators about government surveillance requests in violation of their contracts with the Senate. He urged senators and staff to consider switching mobile carriers for their campaign and personal phones to carriers that will notify them about government surveillance demands.
“While AT&T and Verizon only provide notice of surveillance of phone lines paid for by the Senate, T-Mobile has informed my staff that it will provide notice for Senators’ campaign or personal lines flagged as such by the [Senate Sergeant at Arms],” Wyden wrote. “Three other carriers — Google Fi Wireless, U.S. Mobile, and Cape — have policies of notifying all customers about government demands whenever they are allowed to do so. The latter two companies adopted these policies after outreach from my office.”
Beyond members of Congress, journalists, political activists, people seeking reproductive health care and other law-abiding Americans who could be targeted by the government all have reason to be concerned about secret surveillance of their communications and location data. Wyden’s office also surveyed phone carriers to learn which companies notify their customers about surveillance. His findings are summarized in the chart below. While it is the norm among tech companies to notify customers about government demands, absent a gag order issued by a judge, most phone companies choose to not notify their customers.
