Give Roberts the opportunity to resign if true so this whole thing can end along with the impending scandals. If he is to rule in the opposite with a Trump administration in place, the caterwauling will undoubtedly be deafening. But then again, why even reverse yourself as he would know the opposition will forever hang this over his head.
Catch 22
