U.S. Senators are the type of narcissistic windbags who revel in the opportunity to scold bureaucrats. It gives them the opportunity to fabricate the appearance of being "tough" or "no-nonsense" or whatever on big government waste that irks their constituents. This is especially true when those bureaucrats work for a punching bag like the IRS.
For whatever reason, Mike Johanns (R-NE) figured John Koskinen, the fairly new IRS Commissioner, needed to be reminded that 1,000 or so IRS employees who were not tax compliant received bonus compensation and paid time-off.
It appears Koskinen was ready:
Johanns presses Koskinen on bonuses to tax-delinquent workers. Koskinen: IRS employees have better tax compliance than Hill staffers. Zing!

No word whether Koskinen dropped his mic immediately after making this statement.
