It should be mentioned that this is the Obama administration’s internal review board. There is an independent executive agency tasked with oversight, http://en.wikipedia.org/wiki/Privacy_and_Civil_Liberties_Oversight_Board
While it was created in 2004, Congress confirmed neither GW Bush’s nor Obama’s nominees until August, 2012. But, Congress did not confirm the chair of the committee, so it could not operate. The chair was re-nominated and finally confirmed in May, 2013.
