State Department watchdog says agency produced 'inaccurate and incomplete' responses to public records requests while Hillary Cl

WASHINGTON — A State Department watchdog will report Thursday that public records searches under Hillary Clinton as secretary of state were inaccurate and incomplete.

The agency's inspector general finds her office personnel missed deadlines and didn't meet legal requirements for searching records under the Freedom of Information Act. That included a request seeking the existence of her private email account.

A draft report obtained by The Associated Press also found some requests have taken more than 500 days to process, and faulted ongoing staff shortages. Such delays involve requests for information going back to multiple secretaries and two presidents.

Clinton is the front-runner for the Democratic presidential nomination. She has faced criticism for relying on a private server to conduct official State Department business.
