Keep talking, but nobody's listening
I would admire Michael Dell for sticking with the now-gone council, in the hopes of influencing the president. I would admire that with just about any other president. However, this president is only going to listen to the voices in his head, he's not listening to Michael Dell, or any others, unless they echo what he's already decided. It's just as well that he's disbanded the council - now they can go back to realizing that they were wasting thei time.
