Judicial Watch, the conservative watchdog group, has sued the State Department, accusing it of failing to provide records pertaining to then-Secretary of State Hillary Clinton and her husband, former President Bill Clinton.

The lawsuit, filed on May 28 but just announced Monday, follows an original Judicial Watch Freedom of Information Act request from more than two years ago. Under federal law, the State Department is "to respond to (an) FOI request within 20 business days."

The May 2, 2011 filing was acknowledged as received on May 17, 2011, meaning the State Department was required by June 8, 2011, to respond.

Judicial Watch's original request sought multiple government records of Hillary Clinton's employees, as well as records of her communications via phone and email, specifically those related to personal or charitable relationships with foreign leaders and governments.

The group made its request out of concerns about possible conflicts of interest between Hillary Clinton's official duties and her husband's wide-ranging international presence in the political and business communities.

Judicial Watch is an independent nonprofit group that focuses on waste, fraud and corruption in the federal government.
