The F.B.I. receives solely a small portion of the messages that the Nationwide Safety Company vacuums up: The bureau will get copies of intercepts to and from targets who’re deemed related to a full and energetic F.B.I. nationwide safety investigation. Presently, that quantities to about 3.6 p.c of the Nationwide Safety Company’s targets, a senior F.B.I. official instructed reporters in a information briefing on Monday.
(That would nonetheless be a large quantity of knowledge. In 2019, the latest 12 months for which information is public, this system had greater than 200,000 targets.)
In early 2018, when Congress prolonged Part 702, it amended the legislation partly to require approval yearly by the International Intelligence Surveillance Courtroom of procedures limiting how and when analysts could question the repository for details about Individuals.
