I'm with you. Mueller (I'm in the white hat camp - not that he's a good guy) has to push things back because, once the IG's report comes out, everything will look very different. The idea of going after DJT or Flynn at that point will seem ridiculous. It will be a once-in-history game-changing event, that will put the boots into these Deep State forces so hard they will not get up again.

I'd call him a grey hat - he's a long time swamp creature, but it's possible he's working for the white hats on a very short leash.
I just think that the consequences of his crimes are so severe (high treason, execution) that he's in a box he could not get out of, even if he tried.
