He has not quit. This article is telling him to do so.
One wonders to whom [RR] truly reports if he's willing to stay in his job and continue the attacks on POTUS. He doesn't look like he has the spine for doing what he's been doing. His attempts at meetings with POTUS seem ominous attempts. I've seen a lot of people under stress and I don't think he'd be doing this without significant pressure put on him by some other powerful entity.
Q,
So Omarosa was planted by [RR] in order to record conversations to be used in the [DS] attack to get POTUS using 25A?
