Prior to going out on recess, the Senate was slated to act on the Cybersecurity bill which included a brand new FOIA Exemption to add to 5 U.S.C. 522. This was not an exemption 3 statute, but would have become FOIA exemption 10.
After the exemption was spotted in draft legislation (there was no warning that it was coming nor was there any hearing discussing it), a coalition of non-profits, led by OpenGovernment.org became active in publicizing the provision, including writing senators. In fact, it is believed that the provision was never shown to the Senate's Judiciary Committee, which has jurisdiction over the FOIA before it was put into the legislation. Through the efforts of those opposed to the language, the exemption was pulled from the legislation prior to a planned vote.
However, as there were other problems with the legislation and no actual vote was held before recess. When the Senate convenes again in September it will likely take up this bill again. As such, the FOIA community should stay informed so that the Exemption is not inserted in again prior to passage of the bill.
