Now comes the job hunting or career changing phase. He could go into internet junk mail or crisis management consulting. Maybe open a charm school or a testing lab for polygraph equipment. He has a lot of experience with photography, too.
If he resigns - I can still see the possibility of him throwing his hat in the ring as a candidate for the NYC mayoral race. After all, his dignity will still be intact ;) coupled with his ego - it’s all possible.
