From those many Americans seeking to provide the facts, I offer up a website produced by many, who collectively have put together their best estimate of several interesting statistics. None of these statistics would have been measurable without the current administration.
The data is provided such that you can query into any level you might have interest in. One might consider the personal decision making that goes into resigning from a job. I suggest that it is very rare.
Highlights of the website are on such topics as:
Resignations (Government and Industry)
Sealed Indictments
Eye on the Ball
