Comey's handling of the Clinton investigation is certainly open to second-guessing, something Democrats may never tire of doing because Comey may have cost their candidate the election. But this instead looks like Justice or the White House using the Clinton case as a pretext for dumping Comey in the middle of his investigation of Trump associates. And remember: Attorney General Jeff Sessions, who said in a letter to Trump that he agrees with this decision, had recused himself from the Russia investigation. He should be nowhere near any action that now undermines public confidence in that case.
