US to declassify documents on spy programs, surveillance court

US spy agencies plan to declassify documents about the National Security Agency surveillance programs revealed by former contractor Edward Snowden, and also material related to a secret intelligence court, a U.S. intelligence official said.

The declassified documents could be released as early as this week and were intended to provide the public more information about the programs as part of a commitment by Director of National Intelligence James Clapper for more transparency. The documents would also include information about the Foreign Intelligence Surveillance Court which operates in secrecy, the official said.
