I will defer to you on experience dealing with the VA. The question is, what in Admiral Jackson's background indicates he's capable of doing the job you describe? What you need is someone with experience planning and implementing a major restructuring of a large organization that resulted in better performance once the restructuring was done. Admiral Jackson, while an excellent physician, doesn't have any experience in running a large organization much less remaking it into a more efficient service provider.
Had Admiral Jackson been confirmed then it's highly likely he would have been a failure. And the VA would be no better off.
Don’t disagree about Jackson. But he should have been rejected on the grounds you describe.
But the VA is too big for anyone. You’ve got medical, disability claims, home mortgage guarantees, education. Plus you can’t fire anyone. The guy that just got fired said there were over 2,000 he wanted to fire but couldn’t.
