What Does Mark Penn Do?

So it seems that even though Mark Penn is CEO of Burson-Marsteller and Burson-Marsteller is handling the PR account for Aqua Dots -- the toy that's come into ill-repute for having an adhesive coating that turns into GHB, thus putting children into comas -- Penn has nothing to do with Aqua Dots. Much as he has nothing to do with Blackwater, another Burson-Marsteller client. And how he has nothing to do with Burson-Marsteller's union-busting practice. So what does he do? And how can a CEO be so uninvolved in so much of his own company's activities?
