He’s not under siege enough. (And who wrote that tweet–who out here thinks tRump knows how to spell “siege?”) He won’t be under siege enough until he is completely overrun. And more – prosecuted.
The President has a tendency to make last-minute decisions to fire members of his cabinet shortly after the White House has suggested such a move won’t happen.
He does it this way out of his heartfelt kindness and respect toward the person being fired. He just hates firing people.
Or trampling on their dignity. 
I think the pressure of not being able to tweet about Russia or Mueller or Stormy is starting to get to him.

Usually on Friday evenings.
You mean Mueller-Time?
Translation: “Bye, Scott. You’re so low-energy I’m going to have to throw you under this bus.”
(Ahem.) If Pruitt’s under such a totally siegey siege, maybe he’ll decide to resign. 
Everyone knows what Trump will do except Trump himself. He’s tied himself in knots over this. But there’s more stuff to come out. So Trump is setting himself up to thank Pruitt for his great work.
Trump’s shtick is so, so tired and way beyond its expiration date. Sad.
Uh oh. Trump says nice things about lackeys “under siege”. It’s the kiss of death for both Sessions and Pruitt. Will Don the Con tweet their firing tonight?
The Trump mob (Trump organization and current administration) mantra for consiglieres and capos:
Do whatever you want, but don’t make the Don pay too much to get you off the hook if you get caught. Because if you do, he will leave you on that hook, while he slips off it.
It worked for the old mafia … until the feds came.
“Hey boss, did you just hear a knock on the door?”
The scary part is anyone too sleazy and morally bankrupt to hold down the EPA job, will be THE perfect AG candidate for Dotard.
Pruit is safe as long as he continues to do the extraction industries dirty work.
“TOTALLY under siege”
Partial sieges tend not to effective owing to one or more escape routes.
A difficult concept, but there it is.
In our mirror universe the other Donald Trump is sitting in a sideshow tent biting the heads off chickens.
Do people really believe this stuff?
Um yeah Don. Just like they said Tillerson was on his way out, and McMaster and Shulkin and…
What a fucking baby. But a weird, corrupt, violence-fetish baby. Not a cute baby. Sick, bad baby.
In other words, he’s not quite corrupt enough to be his Attorney General. Another outrage or two ought to do it !
Hell, Pruitt is taking attention away from 45. That is enough to warrant his dismissal.
Oh, now, he’s just talking like a Valley Girl. It’s one of his few endearing traits.
