WASHINGTON (AP) — An independent oversight board reviewing secret government surveillance programs warned the Obama administration that national security agencies’ rules governing surveillance are outdated and need to be revised to reflect rapid advances in technology.

The chairman of the Privacy and Civil Liberties Board, David Medine, wrote to Attorney General Eric Holder and Director of National Intelligence James Clapper, urging that rules governing collection and retention of data about U.S. citizens be updated to “appropriately capture both the evolution of technology and the roles and capabilities of the intelligence community since 9/11.”
