Rience resigned. He didn’t want to be around Mooch. Trump didn’t have to be the bad guy. It worked.
I think it’s better optics to fire someone than to hire a foul mouthed guy that calls up the liberal press to insult people and then fire that guy in two weeks. If it’s true that the mooch sold his business and lost his wife over the deal, that wasn’t really a good way to treat him.
