Auditing your enemies. Nixon wanted a "ruthless son of a bitch".

Obama is getting the same IRS audit results as Nixon.  Are the president and his colleagues lily-white or is this "quacks like a duck, is a duck"?  The Chicago Way.

Nixon fired the IRS commissioner, R.W. Thrower in 1971 for insisting "Sure, we’ll audit them — just like everyone else when their names come up through the regular audit selection process.”  Looking for a replacement Commissioner in May of that year, Nixon "made clear what kind of commissioner he wanted".

“I want to be sure he is a ruthless son of a bitch,” he was recorded as saying, “that he will do what he is told, that every income tax return I want to see I see” and “that he will go after our enemies and not go after our friends.”
