The US has set a new record for denying and censoring federal files under the Freedom of Information Act, analysis by the Associated Press reveals. For the second consecutive year, the Obama administration more often than ever censored government files or outright denied access to them under the open-government legislation. The government took longer to turn over files when it provided any, said more regularly that it couldn't find documents, and refused a record number of times to turn over files quickly that might be especially newsworthy. It also acknowledged in nearly one in three cases that its initial decisions to withhold or censor records were improper under the law - but only when it was challenged. Its backlog of unanswered requests at year's end grew remarkably by 55% to more than 200,000. Citizens, journalists, businesses and others made a record 714,231 requests for information. The US spent a record $434m trying to keep up. The government responded to 647,142 requests, a 4% decrease over the previous year. What we discovered reaffirmed what we have seen all too frequently in recent years," [The AP's chief executive, Gary] Pruitt wrote in a column published this week. "The systems created to give citizens information about their government are badly broken and getting worse all the time."
