This would definitely be a very significant first and a good warning to others in the IRS. 

Rep. Jim Jordan Says House Will Impeach Head of IRS

Unfortunately, the IRS criminals are really just pawns for the masterminds of the plots to use government power, bHo and his number one partner in crime, Valerie Jarrett, who have already been given immunity from impeachment by our gutless GOP rulers.  

Who knows if impeaching Koskinen for his very obvious and blatant acts of perjury and obstruction of justice will make any real difference in the big scheme of things.  If he is actually convicted for his crimes, it’s safe to say that he will receive a pardon from the White House.

Judge tells IRS it can’t hide White House emails

IRS must say if White House sought taxpayers’ information: Judge

This judge shouldn’t hold her breath waiting for cooperation from IRS. They have been as helpful and honest as Hitlery Clinton has been with the multiple investigations into her crimes.

Imagine that.  Our most highly personal and confidential financial information is still not totally secure in the hands of our good buddies at the agency we all love, IRS.  Big Brother is letting us all down here.

IT boss ‘blown away’ that IRS backup tapes in Lerner case erased, watchdog says – It’s amazing that anyone could still possibly believe that the erasures were accidental.

While it’s doubtful the GOP has the guts to take on the bHo Regime, it is interesting that the level of known corruption at IRS has reached this point.  Koskinen has obviously been actively involved in the cover-up of Lois Lerner’s crimes, including lying in his testimony to Congress. Are his days as top dog at IRS numbered?
