'In less than an hour, President Trump found a way to impugn the integrity and threaten the livelihoods of nearly all of the country’s top law enforcement officials, including some he appointed, for one simple reason: They swore an oath to defend the Constitution, not him. Mr. Trump’s cavalier attitude toward this carefully designed system is an affront to the people who have spent their careers respecting and protecting it. It’s also the clearest sign yet that he values the rule of law only to the extent that it benefits him personally.In the end, Mr. Trump is concerned with nothing so much as saving his own hide, which means getting rid of the Russia inquiry for good. He previously said this was why he fired Mr. Comey, and it may yet be the undoing of Mr. Sessions, Mr. Rosenstein and Mr. Mueller.'
