Donald Trump's White House is positively toxic. Friday's news alone was a tour de force of the all-encompassing virulence that's now seeping from Trump throughout the entire executive branch and everything it touches.

Trump's days start with a crack-of-dawn phone call about everything Russia that's clearly aimed at distracting him and his thumbs from Twitter. Why his aides aren't just jingling some keys in front of him is a mystery, but the call is nothing but a venting session intended to soothe a sulking and brooding pr*sident.

Trump's entirely self-generated Russia predicament apparently has him miffed at his White House counsel Don McGahn. Somehow, McGahn has failed to stop Trump from engaging in a series of self-defeating, ill-advised, impulsive, and often petulant behaviors that have now made him the central focus of an obstruction probe. And make no mistake, that's McGahn's fault in Trump's view.
