Daniel Drezner has a pretty good roundup.
Looks like Wolfowitz' problem is bigger than I first thought. The oversized salaries for Kellem and Cleveland look significant. I'm not sure I buy into the story about him blocking loans "capriciously"--that could be axe grinding. But it's pretty clear that wrongly or rightly he's rubbed a lot of people the wrong way. Another Rumsfeld, if you will.
Still, I'm struck that his critics are the same people that opposed his appointment, and they weren't criticizing his business ethics at that point.
