This New York Times article documents the Bush administration’s successful efforts to prevent the public release of a range of government documents largely based on post 9/11 security concerns. Members of Congress have been fighting these efforts on several fronts, including protesting the removal of data from government agency websites for what has been interpreted as partisan political, not security, reasons.
For some perspective on this issue, I take you back to 2001, and Executive Order 13233, Further Implementation of the Presidential Record’s Act, issued November 1, 2001 by President Bush, as well as this related New Republic article in response to the order.
