I fully expect him to stir up as much shit as he possibly can on his way out, and after -- way after, even. It will be an integral part of his brand. He'll play that tune till the day he dies, and leave it for his children to inherit for their personal and political gain.
And then there's all the classified info he has access to. Who know what he's learned, and how he'll use it to his advantage after he's out.
