I'm wondering if Flynn comes back as special prosecutor for Hillary.

Trump promised many times he would appoint a special prosecutor to pursue Hillary.

However, this was also pointed out that he legally doesn't have the ability to appoint a federal employee to pursue a specific individual, let alone one that was his key political opponent.

Now, however, four months later, Jeff Sessions is AG and has said in his confirmation hearings that he will recuse himself from Hillary related investigations because of his negative comments as a senator during the campaign create the opportunity for him acting impartially.

So there is now an opening for trump to do just what he claimed, despite the denials of his ability to do so.

End result, if Hillary faces further investigation, a different person will have to lead the legal prosecution.

This is very speculative, but Flynn is now available, and has a history of speaking out about Pizzagate.

Trump has so far made good on many campaign promises early on and this would be a power move on many levels with one strike.
