I think we're going to be learning a lot about Inspectors General in the coming weeks and months.

Our federal bureaucracy has a lot of IGs. Their offices have the crucial responsibility to prevent and detect waste, fraud, abuse, and mismanagement. When they operate at their best, they are vital to uncovering and disclosing unethical, irresponsible, and criminal behavior. Unfortunately, they are staffed by human beings and have been rightly criticized for persecuting some whistle blowers.

The Council of the Inspectors General on Integrity and Efficiency (CIGIE) is an independent entity established within the executive branch to address integrity, economy and effectiveness issues that transcend individual Government agencies and aid in the establishment of a professional, well-trained and highly skilled workforce in the Offices of Inspectors General. https://www.ignet.gov/

Here's some specific information about Steve Linick at State.

I wouldn't be at all surprised if we start hearing from more IGs throughout the Executive branch as 2019 unfolds.
