Couldn't agree more. I guess if your expectation was an AG in the mold of Holder and Lynch, thoroughly political and controlled by the President, then Trump made the mistake of nominating a man of principle, integrity, and wedded to the concept of the Rule of Law. If Trump thinks he can find an AG who will do whatever he commands, then it will be a long search for a replacement.
The reverberations of this fit of pique will be felt among his supporters. I don't think he understands how respected Sessions is. Will more resignations follow, including Steve Miller and Kris Kobach? Who will be the next scapegoat?
That theme and variations of it are described in comments at CTH, Transcript of President Trump Wednesday Interview With New York Times
Examples ...
Misdirection. Trump is a magician. He puts stink on Borris the Squirrel and the media hounds chase it for 9 months. Sessions is going after the pedophiles. Trump hates pedophiles, hates them. Really hates them. Sessions is doing exactly what Trump wants, Sessions has no time to deal with Borris the Squirrel chasers.Take down the pedo's and watch Swamp, Inc. dry up.
One more thing, Trump said in bold letters he has no control over what Sessions does. That is the message he put on a billboard in this interview. Something is coming that requires Trump be far away from it.
President Trump understands that he cannot depend on Congress, or even midterm elections, to give him the support he needs. He needs blackmail. I know that sounds bad, but it is the truth. He has to use the DoJ as a weapon.
Most of Congress is dirty as hell. Trump knows this. Hell, it's the worst kept secret in Washington. Everyone in the "swamp" from Congress to various officials are creatures of their own self-enrichment and the only thing that takes precedence to that is saving their own skins.
Thus, President Trump, in order to push forward his agenda, will need to threaten these people with exposing their corruption. He will have to make an example or two up front, but following that he will hold all of the leverage.
Let me be clear: this is not how government should work. But President Trump did not create nor cause the corruption that already exists. So he can, clear of conscience, use it to work for the American people.
To do this, he has to have an AG who he can absolutely trust 100%. Sessions fits the bill there.
3. Sessions loyalty and public backing of Trump in the campaign is a huge asset to Trump, but also a liability to him. It means that Trump's enemies can always question Sessions' independence if he moves against major swamp figures, esp Obama or Clinton.
... The strategy has therefore been to create cover for Sessions so that when the hammers start to drop, he is seen as independent and squeaky clean.
5. To achieve this, Trump & Sessions have since his appointment as AG (i) minimized public contact with each other, with Sessions keeping a relatively low profile working in the shadows, (ii) engineered Sessions recusal from `muh Russia' (anyone who thinks Trump wasn't fully in on this doesn't understand how Trump operates), (iii) appointed Rosenstein, who is not pro-Trump - again, strengthening Sessions' appearance of independence and now (iv) Trump criticizes Sessions in the NYT of all places, which amplifies the perception (to a liberal audience) that Trump has no control over Sessions / may have turned on Sessions.
