The dust has only just begun to settle. Based on Special Counsel Robert Mueller’s specific finding of “no collusion” that should be the end of the day on that. The curious way he and (separately?) the Attorney General handled the obstruction case, though, is still up for grabs. And it will probably await their testimony before the Congress. And testify, Mueller surely will. Attorney General William Barr has already been called.

But the talking heads haven’t much been talking about why Mueller didn’t insist—if necessary, by grand jury subpoena—that the president give his own “oral account” to Mueller, or to his grand jury. Why did Mueller let him off the hook in this regard? Did he fear he would lose a constitutional fight? Maybe. Did he fear the unseemliness of such a battle with a sitting president? Who knows? Nonetheless, those issues will apply solely to an investigation of the president of the United States.
