WASHINGTON (AP) — An analysis shows the government censored in the name of national security files requested last year by the public under the Freedom of Information Action more often than any time since President Barack Obama took office.

The analysis by The Associated Press found the administration answered its highest number of requests so far for copies of government documents, and slightly reduced its backlog of requests from previous years. But, led by the Pentagon and CIA, it more often cited legal provisions allowing the government to keep records or parts of its records secret, especially a rule intended to protect national security.

The government turned over all or parts of records in about 65 percent of requests. It fully rejected more than one-third of requests, a slight increase over 2011.
