Conclusion: I think President Trump and AG Sessions may be playing an extremely deep game here. This could all be strategery.

It's the only reason that explains why Sessions hasn't resigned.

-- [playing a game] It's the only reason that explains why Sessions hasn't resigned. --

First a glib but accurate observation. Resignation is the ultimate recusal.

Assume for the sake of argument that Sessions is disloyal, or just plain self-centered. he could ignore the public humiliation as a function of forcing Trump to fire him, rather than resigning.

Sessions might stay in out of pique.

All sorts of options, when dealing with human affairs.
