The Associated Press said Wednesday that it was considering legal action over unfulfilled Freedom of Information Act requests for government documents covering Hillary Rodham Clinton’s tenure as secretary of state.

In its requests, the AP asked for her full schedules and calendars and for details on the State Department’s decision to grant a special position to a longtime Clinton aide, Huma Abedin, among other documents. The oldest request, the news organization said, was made in March 2010.

“We believe it’s critically important that government officials and agencies be held accountable to the voters,” said AP’s general counsel, Karen Kaiser. “In this instance, we’ve exhausted our administrative remedies in pursuit of important documents and are considering legal action.”

The statement comes after the revelation this week that Mrs. Clinton used a personal email account for her government business, an unusual practice that some have suggested insulated her correspondence from the eyes of investigators and the public.
