Understanding the strategy behind President Trump's twitter slam of AG Sessions?

. . .  "but President Trump could have fired him anytime he wishes.  And he would have, if he really thought the prosecutions of his mortal enemies are going nowhere.

Thomas Lifson  "I have a strong suspicion that the current kerfuffle between President Trump and Jeff Sessions is part of a strategy, not merely – as the left has it – a rogue president shockingly, immaturely, and inappropriately attacking his attorney general on Twitter.

"By now, you have probably seen the tweet in question:

Why is A.G. Jeff Sessions asking the Inspector General to investigate potentially massive FISA abuse. Will take forever, has no prosecutorial power and already late with reports on Comey etc. Isn’t the I.G. an Obama guy? Why not use Justice Department lawyers? DISGRACEFUL!

"Occam's Razor suggests that the president means it and that he really wants DOJ prosecutors charged with going after Comey and is genuinely angry at Sessions.  But I always see Donald Trump as a master of the video narrative, an expert crafter of story arcs that work to his advantage, and which often lure his opponents into positions that redound to his benefit once all the facts and drama have played themselves out before the nation's eyes.  Never forget that Donald Trump is the most successful reality television producer in the history of the medium.  And never forget that he played the media like a Stradivarius violin during the campaign, exploiting their predictable outrage." . . .

What if A.G. Sessions is already conducting serious investigations and has developed evidence that will result in indictments for misbehavior in the surveillance of the Trump campaign and in the FBI?  The very last thing Sessions (or Trump) would want is for Sessions to be seen as Trump's hit man, going after his political opponents.  Wouldn't it better, instead, for Sessions to be regarded by the mainstream media as someone sympathetic, because the POTUS has attacked him? This dispatch from Trump-hating CNN makes my point:

On the other hand... NRO declares, "We’re with Jeff Sessions"

The president has a point in urging an investigation by Justice Department prosecutors, although nothing justifies his blunderbuss tweet and ongoing campaign of humiliation against Jeff Sessions.
