Officials from U.S. intelligence agencies backed reauthorization of Section 702 of the Foreign Intelligence Surveillance Act ahead of a U.S. Senate subcommittee hearing Tuesday. One official characterized a potential lapse or "unusable" modifications to Section 702 as "grave national security risks." The support for full reauthorization came as 21 advocacy groups joined on a letter urging reform of Section 702. Meanwhile, the Office of the Director of National Intelligence issued a report regarding purchases of commercially available personal information by the U.S. intelligence community.
