Oversight board examining surveillance issues hears from lawyers for NSA, intelligence agency

An independent board examining clandestine U.S. surveillance programs is hearing from senior lawyers for the National Security Agency and other government departments amid new concerns about the secret operations from Congress, technology companies and European allies.

The five-members of the Privacy and Civil Liberties Oversight Board who gathered Monday in Washington are appointed by President Barack Obama but report to Congress. The board has set no deadline but has been meeting for months with national security officials to scrutinize the surveillance programs and their impact on civil liberties.

The committee planned to hear from Rajesh De, the NSA's general counsel, and Robert Litt, top lawyer for the Office of the Director of the National Intelligence, as well as a senior U.S. judge, James Carr.
