I predict that simply as a function of attempting to save face, the press will continue to ignore the simple fact that Comey usurped the role of prosecutor; and by agreement, nobody in the prosecutor's office voiced an objection.
Rosenstein's letter will be buried under an avalanche of meaningless speculation and illogical criticism (for example, "timing" or "to stifle the Russia investigation").
Quoting Eric Holder’s words in support of Comey’s termination is pure gold.
