WASHINGTON –U.S. Sen. Mark R. Warner (D-VA), Vice Chairman of the Senate Select Committee on Intelligence and a member of the Senate Banking and Finance Committees, today sent letters to Twitter and Google parent company Alphabet, requesting information about any data sharing agreements between the companies and Chinese vendors. The letter follows a disclosure earlier this week by Facebook that the company has partnerships with Chinese telecom companies including Huawei that allow them to access Facebook users’ non-public data. 

“Since at least October 2012, when the House Permanent Select Committee on Intelligence released its widely-publicized report, the relationship between the Chinese Communist Party and equipment makers like Huawei and ZTE has been an area of national security concern. Since then, numerous articles in the tech trade press have focused on concerns by American and allied intelligence agencies that products from Chinese device makers, such as Lenovo, have security vulnerabilities that could allow Chinese intelligence to access data stored on, or transmitted by, devices.  And the New York Times reported in 2016 that firmware found in low-end smartphone devices, such as those of Huawei and ZTE, continually transmitted local data to Chinese severs, potentially for foreign intelligence purposes,” Sen. Warner wrote to the two companies today. 

It is publicly known that Alphabet has entered into strategic partnerships with Chinese mobile device manufacturers, including Huawei and Xiaomi, as well as with Chinese technology platform Tencent. In light of Facebook’s recent revelations, Sen. Warner requested that the company provide information about those partnerships, as well as any other agreements that Alphabet may have entered into with third-party vendors based in China. A similar request was posed to Twitter. 

Sen. Warner’s letter to Alphabet CEO Larry Page is available here. His letter to Twitter CEO Jack Dorsey is available here.
