The Defense authorization bill working its way through Congress has set off alarm bills in the FOIA community as a draft of the bill rewrites FOIA Exemption 2 and overrides a 2011 Supreme Court decision that limited the Exemption. Politico has this on the issue.
Since the Supreme Court limited the use of Exemption 2 in 2011 there has been little legislative action to protect information that may not be protected by other exemptions. Agencies have broadened the use of Exemption 7(e) and (f), but those exemptions may not always be applicable to information formerly protected by Exemption 2. While there may be some agreement that there are a few areas of information that should be protected, it is definitely not on the language in the draft authorization bill. Further, the committees of Congress with FOIA jurisdiction (that are both currently dealing with amendments to the FOIA) should be the committees that bring forth the bill. It should not be part of a Defense budget bill.
