Paul Ryan's missed opportunity
All those Republican apologists for poor, innocent Trump who just didn't know the ins and outs of dealing with arcane Washington mores--you know, like ethics that a fourth-grader would understand--really should have taken it upon themselves to tutor poor innocent Trump in the ways of government. Why didn't Mr. Rectitude Ryan take it upon himself, since it's been clear to all of us that Donald has no idea of how things governmental work, to spend time with him, explaining things to him in a way he could understand?
I agree that Comey (who we know is a villain for what he did to Hillary) is a coward. He should have said, from the start, "Mr. President, you simply cannot say things like that to me," and he should have given the "leaked" memo directly to the media. I think anyone who is the head of the FBI should be able to do these two things at least, and do them without thinking too much about it. The head of the FBI is not like you and me; his or her responsibilities outweigh our own by unimaginable magnitudes, so I don't have much sympathy for those who try to be understanding about Comey's cowardice.
But Paul Ryan's responsibilities also outweigh our own, and in this case, even Comey's. As speaker of the house, he has enormous power in this totally Republican government, and if he realized the President had serious gaps in his understanding, it was his duty as an American to step in and try to remedy the situation. And ditto for all the other Republicans who jumped on that bandwagon--why didn't they do anything about it before it came to this pass?
Edited to add (although it seems I'm too late)
My point is of course rhetorical. I understand full well that Ryan's excuse for Trump's behavior is total bullshit. I was in my own way calling Ryan on his bullshit.
