You’ve been warned: a fight over the government’s ability to spy on its own citizens is coming to Congress. Section 702 is up for renewal again in December.
Section 702 grew out of an illegal post-9/11 program called Stellarwind, exposed by NSA whistleblower Tom Drake. It refers to a provision of the Foreign Intelligence Surveillance Act (FISA) that was enacted in 2008. It authorizes the government to collect the communications of non-Americans located outside of the United States for the purpose of obtaining foreign intelligence information.
