White House spokesman Eric Schultz said in a statement that during the past year, the government "processed more requests, decreased the backlog, improved average processing times and disclosed more information pro-actively." Schultz said the improvements "represent the efforts of agencies across the government to meet the president's commitment to openness. While there is more work to be done, this past year demonstrates that agencies are responding to the president's call for greater transparency."The administration cited exceptions built into the law to avoid turning over materials more than 479,000 times, a roughly 22 percent increase over the previous year. In many cases, more than one of the law's exceptions was cited in each request for information. In a year of intense public interest over deadly U.S. drones, the raid that killed Osama bin Laden, terror threats and more, the government cited national security to withhold information at least 5,223 times â¿¿ a jump over 4,243 such cases in 2011 and 3,805 cases in Obama's first year in office. The secretive CIA last year became even more secretive: Nearly 60 percent of 3,586 requests for files were withheld or censored for that reason last year, compared with 49 percent a year earlier. Other federal agencies that invoked the national security exception included the Pentagon, Director of National Intelligence, NASA, Office of Management and Budget, Federal Deposit Insurance Corporation, Federal Communications Commission and the departments of Agriculture, Commerce, Energy, Homeland Security, Justice, State, Transportation, Treasury and Veterans Affairs. U.S. courts are loath to overrule the administration whenever it cites national security. A federal judge, Colleen McMahon of New York, in January ruled against The New York Times and the American Civil Liberties Union to see records about the government's legal justification for drone attacks and other methods it has used to kill terrorism suspects overseas, including American citizens. She cited an "Alice in Wonderland" predicament in which she was expected to determine what information should be revealed but unable to challenge the government's secrecy claim. Part of her ruling was sealed and made available only to the government's lawyers.
