Oh, you wanted to limit that to the WH. Hummmmmm, well, I would have tossed the entire staff, every last one of them down to possibly even the janitor. Bannon isn't great but I would keep him around possibly as the 10th man kind of thing. I would likely not have had the kids so involved. Flynn was just plain stupid. I would have also culled the entire vetting team on that crap.
And there have been far far worse shit stains in the WH than Trump.
