Statutory offices of inspector general (OIG) consolidate responsibility for audits and investigations within a federal agency. Established by public law as permanent, nonpartisan, independent offices, they now exist in more than 60 establishments and entities, including all departments and largest agencies, along with numerous boards and commissions. Under two major enactments -- the Inspector General Act of 1978 and its amendments of 1988 -- inspectors general are granted substantial independence and powers to carry out their mandate to combat waste, fraud, and abuse. Recent laws have added offices, funding for special operations, and law enforcement powers to OIGs in establishments. Recent initiatives have set up mechanisms to oversee the Gulf Recovery Program, while various legislative proposals in the 110th Congress are designed to strengthen the IGs' independence and establish new posts, among other matters.
