Could it be a precursor to privatising the VA. This has been alluded to Trump thinking on the matter. This jerk with his background might be a good choice if this is the case.
Still, I have to agree that it is a disappointment.
Any Obama appointee is a very liberal pro abortion, sodomite-loving democrat. Trump could have left the toothpaste salesman in charge until he found a qualified republican nominee. But he plays politics with vets by trying to make the dems happy by doing nothing about the VA mess.
