The National Security Agency took disciplinary actions against analysts who intentionally overstepped their legal authority, according to a government official familiar with the actions.

The agency informed Congress of the privacy violations and subsequent punishments, the official said. It is unclear whether any NSA analysts lost their jobs over the incidents.

The NSA acknowledged on Friday that analysts had deliberately violated privacy rights multiple times in recent years. The agency had previously said that other legal violations were inadvertent and largely the result of technical glitches.
