:: Bannon, Tillerson, Scaramucci, and a few others who were briefly part of the Trump administration. ::
Some became moths that ending up flying too close to the bug-zapper.
Some were attractants for rumors and media scrutiny.
Some were assigned to canary traps.

You can also look at them as casualties. This administration, any admin really, is at political war and there are political casualties of that war, some friendly, some foe, but I think you have to come to the WH knowing that your career may be affected by political exigencies beyond your control.
What do you make of the allegations that Tillerson is a very guilty illuminati etc.?
