Two senators have written to the U.S. Department of Defense about reports that President Donald Trump may still be using an unsecured Android phone, including to communicate through his Twitter account. The senators are worried that the phone may be vulnerable to hackers who could access sensitive information by turning on audio recording and camera features, as well as engaging surveillance tools that allow location and other information tracking features” They want information from DoD and its Defense Information Systems Agency (DISA) on whether Trump received on or before his inauguration a secured, encrypted personal smartphone and is using it.”]
