Why Walpin was fired and the Obama scandal

Powerline explicates it in 'It's all about the money': 

So the investigation had to be swept under the rug quickly, and Walpin had to go. Obama had one of his White House lawyers call Walpin and demand that he resign within an hour. When Walpin refused to quit, Obama fired him without giving a reason other than his supposed lack of "fullest confidence" in Walpin. This certainly violated the spirit, and may have violated the letter of the 2008 Inspectors General Reform Act, which Obama co-sponsored. (I think it probably did.) This is classic Obama--ignoring a statute which he himself had sponsored just a year earlier.

Everything that we know about the Walpin episode so far contributes to the picture we are getting of the Obama administration--its fondness for bullying tactics; its lawlessness; its cronyism; its lack of transparency; its eagerness to crush anyone who gets in the way of Democratic Party corruption. I'm afraid we're going to see many similar stories over the next 3 1/2 years.
