( CNN ) -- FBI agents searched the home of veteran diplomat and Pakistan expert Ambassador Robin Raphel in October as part of a counterintelligence investigation , three U.S. government officials told CNN . As part of the investigation , Raphel 's State Department office was searched and sealed , two of the officials said . It 's unclear whether she is the target of the investigation , or what agents were searching for . The officials said it is an ongoing investigation and no charges have been filed . The investigation was first reported by The Washington Post . `` We are aware of this law enforcement matter . The State Department has been cooperating with our law enforcement colleagues , '' State Department spokesperson Jen Psaki said . Psaki added that Raphel is `` no longer a department employee . '' At the time of the raid , Raphel , a retired career Foreign Service officer , was an adviser on Pakistan under a limited , renewable contract to the State Department 's Special Representative for Afghanistan and Pakistan , where she administered nonmilitary aid and economic grants . It is unclear , however , whether the inquiry is related to her work on Pakistan . Senior State Department officials said Raphel 's security clearance was pulled last month , at which time she was placed on administrative leave . Her contract , which expired on November 2 , was not renewed . The officials describe the investigation as a counterintelligence investigation , which typically refers to allegations of spying on behalf of foreign governments . Officials declined to describe the exact nature of the investigation . Raphel , the former assistant secretary of state for South Asia and ambassador to Tunisia , spent much of her career working on Pakistan and South Asia . Raphel was well-liked and respected by her colleagues and often outspoken about what she saw as flaws with U.S. policy toward Pakistan . Raphel 's State Department biography says she began her career as a CIA analyst before serving 30 years in the Foreign Service . She retired from the State Department in 2005 , but returned in 2009 to work as an adviser to the late Richard Holbrooke , appointed by then-Secretary of State Hillary Clinton as the first special representative for Afghanistan and Pakistan . CNN attempted to contact Raphel , but messages have not been returned .
