President's Intelligence Advisory Board (PIAB). Under the PIAB is the Intelligence Oversight Board (IOB), which is used to carry out investigations and initiate analysis activities for the President. The PIAB members are appointed by the President and are usually individuals with relevant experience. In 2008, President George W. Bush by Executive Order removed some oversight powers from the IOB, critics argue that the changes have weakened oversight capabilities. Previously, if the IOB learned of allegedly illegal or contrary to executive order intelligence activity, it notified both the president and the attorney general, now however, the IOB must refer matters to the Justice Department for a criminal investigation. In addition, the IOB lost the authority to oversee each intelligence agency's general counsel and inspector general. The main issue with the PIAB is concerns, since they are appointed by the president, there may be politicization of their recommendations. Offices of Inspector-General Under each cabinet position and intelligence agency, the Office of the Inspector General (OIG) and the General Counsel, have oversight responsibilities (see The Inspector General Act ). The OIG reports to the Secretary of the department and/or the director of their agency as well as Congress. The OIG are tasked with the following Conduct independent and objective audits, investigations and inspections Prevent and detect waste, fraud and abuse, Promote economy, effectiveness and efficiency, Review pending legislation and regulation Keep the agency head and Congress fully and currently informed. The OIGs for the Intelligence Community include: Inspector General of the Intelligence Community Central Intelligence Agency Office of Inspector General Department of Defense Office of Inspector General National Security Agency Office of the Inspector General Defense Intelligence Agency Office of the Inspector General National Geospatial-Intelligence Agency Office of the Inspector General Office of the Inspector General of the United States Air Force Office of the Inspector General of the United States Army Office of the Inspector General of the United States Navy Office of the Inspector General of the Marine Corps U.S. Space Command Inspector General U.S. Department of Energy Office of Inspector General Department of Homeland Security Office of Inspector General United States Department of Justice Office of the Inspector General Department of State Office of Inspector General U.S. Department of the Treasury Office of Inspector General It is possible for a separate Inspector General to conduct an investigation if instructed by the Council of the Inspectors General on Integrity and Efficiency.
