WASHINGTON (AP) — The Obama administration has a way to go to fulfill its promises from Day 1 to become the most transparent administration in history.

More often than ever, the administration censored government files or outright denied access to them last year under the U.S. Freedom of Information Act, cited more legal exceptions it said justified withholding materials and refused a record number of times to turn over files quickly that might be especially newsworthy, according to a new analysis of federal data by The Associated Press.
