My theory on why Pruitt still has his job:

[George II]

He has a copy of the pee tape.

1. Oh, good grief. How would he have gotten it, assuming it exists at all?

More importantly, Trump doesn't care about crap like that. He knows his cult members would stick with him if he peed on each of them personally. The pee tape, if it exists, is of no consequence; what the Russians have on Trump is all about money. And Pruitt keeps his job because Pruitt is making the base happy by gutting environmental regulations and Trump doesn't care about ethics.

2. he is exactly what trump wants

he wants to shrink if not eliminate EPA. I bet Pruitt intentionally drives the morale down. That’s how you bancrupt companies. Induce flight of top talent out of EPA.

[Wellstone ruled]

3. These two names.

Koch and Ichan.

[dchill]

4. I think Trump just likes the distraction.

[FakeNoose]

5. I think he's getting big PAC money donations to the RNC and to Trump's campaign

... besides the other things mentioned up-thread. He must be hitting the government contractors really hard for donations, otherwise why would he need a sound-proof booth or a secure private email server?

6. The Koch brothers are in control. With one phone call they could turn the Evangelicals against him
