Its my understanding that only happens if Holder directs it to happen.Then we find out if anyone in the Justice Department has any honor. If there are such people. Holder won't be able to enforce his orders. If not, they'll all hang together (to avoid hanging separately).Or, if it happens without Holder directing it to happen, then Holder can direct Machen to do nothing.
That's just my humble, uninformed opinion.
