“Throughout the tenure of Secretary of State Hillary Clinton, there was no permanent inspector general at the State Department. Moreover, President Barack Obama did not nominate anyone for that position while Clinton was Secretary. Although the office remained running under Harold W. Geisela State Department employeethe “Government Accountability Office, lawmakers from both parties and nonprofit groups” criticized the delay in identifying a nominee, and called for the position to be filled by an inspector independent of the State Department.”
