I personally don't know the details about this Chicago situation. I mean it's entirely possible that the city provided access to the pension fund but it was the union that made the actual contributions. But who knows? As AuntyM says we're talking about Chicago here so anything is possible.

I will agree, though, that this does sound damn fishy. Looks like he took advantage of a loophole in the law. And what kind of union leader retires to go to work for a hedge fund?
