 Since Stevens had not yet been sentenced, Holder's action effectively vacated Stevens' conviction.Prosecutor Marsh, although he had been removed as the team leader of the Alaska probe's prosecution, well prior to the Stevens debacle, had become episodically depressed as a result of the extreme length of the investigation into the conduct of the team involved in the Senator's case.This was exacerbated by his consequent reassignment to less favorable international duties, pending resolution of the inquiry, though he had anticipated complete exoneration.
