The way I see the EPA situation.
1) The EPA has been operating as a major slush fund/corrupt for several decades now (wonder why..).
2) During that time the amount of slush fund/diverted funds created a huge web going to numerous politicians and groups through non profit funneling.
3) Pruitt has come in and has begun to clear out the situations.
4) HOWEVER, since the shady dealings were so vast and so shadowed (ie: behind the veil) they are now coming out and attacking him for the very thing they did.
In other words, they are literally blaming him for slush funds created, setup and abused by them but due to the web they created it forces them to have to find the paper trail to prove it wasn't him but was them.
This is a common tactic we have seen employed by the left/corrupt actors this past year alone where they will come out, use their controlled media/social media and push the narrative that the crime was done by PERSON A when, in fact, it was PERSON B who did it. They did this with Trump Russia, blaming Trump for the "created videos" lately and so on. Common tactic they use.
