Senate Majority Leader Mitch McConnell (R-KY) is attempting to place the Cybersecurity Information Sharing Act (CISA) as part of the pending National Defense Authorization Act (NDAA) without allowing any debate and amendments on the CISA itself.
The problem for the FOIA community is that the CISA creates a very broad FOIA exemption as described in this memo from Open the Government. None of the congressional committees in the Senate or the House that have jurisdiction over the FOIA have had any hearings on this proposed exemption. Minority leadership of the Senate have urged McConnell to bring CISA to the floor as a stand alone bill so that it can be debated and amended.
There is no doubt that Cybersecurity is important; however, as the Patriot bill debate should have demonstrated to McConnell, pushing through legislation without allowing changes for privacy and transparency isn't the best route to take.
Update: Politico has this detailed article on the entire bill and the Democrats planned filibuster.
