Former US congresswoman Tulsi Gabbard's ascendance to director of national intelligence last month signaled a major shift in views toward government surveillance at the highest rung of the US intelligence community. Major privacy groups this week urged Gabbard to declassify information concerning Section 702 of the Foreign Intelligence Surveillance Act (FISA)the nation's cornerstone wiretap authority ... known to vacuum up large quantities of calls, texts, and emails belonging to Americans. The groups privately urged Gabbard this week to declassify information regarding the types of US businesses that can now be secretly compelled to install wiretaps on the US National Security Agency's (NSA) behalf. While it's no secret that the government routinely compels phone and email service providers like AT&T and Google into conducting wiretaps, Congress passed a new provision last year expanding the range of businesses that can receive such orders. Legal experts had warned in advance that the provision was far too ambiguous and likely to vastly increase the number of Americans whose communications are wiretapped. But their warnings were not heeded. In response to questions from the US Senate ... Gabbard backed the idea of requiring the Federal Bureau of Investigation to obtain warrants before accessing the communications of Americans swept up by the 702 program.
