At this point, they're ALL unindicted...
They'll probably stay that way, too...
At some point, there was enough there to bring Rosenstein into a grand jury room (willing to wear a wire into the White House would get you serious charges). I think the WH lined up the deal...you get the Mueller report to end in six months, with no additional heat for the President, and we let you retire and slide away with no charges. He’s kept his end of the deal, and I can’t see him dragged into a fresh mess now.
