The ACLU joined this June 8 coalition letter sent to Senate leadership, urging passage of proposed amendments that would strike three exemptions to the Freedom of Information Act (FOIA) from the National Defense Authorization Act for FY 2017 (S. 2943) currently under consideration by the Senate. The amendments, from Senators Grassley and Leahy, are critical to protect the FOIA’s integrity and would eliminate exemptions relating to military tactics, techniques, and procedures; the treatment of critical infrastructure security information by State and local governments; and confidentiality of information provided to the Department of Defense by transportation network companies accessing Department installations. The letter stresses that amendments to the FOIA should be given careful consideration by committees of jurisdiction and through public hearings in order to ensure the bill promotes transparency and accountability, while allowing the government to withhold information that truly requires protection.
