The trouble is that while Rosenstein got what he wanted, Trump’s idea of correcting the record was to say publicly exactly the thing about a law enforcement officer that makes his continued service in office impossible: That Trump had used his deputy attorney general as window dressing on a pre-cooked political decision to shut down an investigation involving himself, a decision for which he needed the patina of a high-minded rationale.

Once the President has said this about you—a law enforcement officer who works for him and who promised the Senate in confirmation hearings you would show independence—you have nothing left. These are the costs of working for Trump, and it took Rosenstein only two weeks to pay them.

The only decent course now is to name a special prosecutor and then resign.
