(BLOOMBERG) — The National Security Agency for about three years violated restrictions on checking U.S. telephone records for surveillance and misled judges on how the data was used, intelligence officials said.
The agency on a daily basis improperly checked a select list of phone numbers against databases containing millions of call records, without meeting the necessary standard, according to documents released by the Office of the Director of National Intelligence to privacy groups today in response to lawsuits.
The violations occurred between May 2006 and January 2009 and involved checks on as many as 16,000 phone numbers, including some based in the U.S., said two senior intelligence officials with direct knowledge of how the program operated. They asked not to be identified in order to speak about sensitive matters.
