It's hard to sense humour on paper. It's best for government agencies to leave it to the onion articles

"I didn't think it needed to be said due to how obvious it is.
But the far-right, Trump included generally whinges about political correctness... And then goes ahead and promotes political correctness because it fits in with their narrative."

>But this isn't Trump we're talking about: Mark W. Menezes and Steven Winberg are NOT Trump.

Trump is the leader. The issue starts from the top, always does.

Trump is president but he doesn't control everyone in his administration 24/7, 365.

That is true, he doesn't directly control. However he does influence, and very strongly at that. The entire DoE has been influenced and constructed by the Trump Administration. The problems stem from the admin as a whole.

No!

He doesn't need to.

Trump has officials that he promotes and supports directly underneath him to push his and his parties stance on various topics of interest.
The Republicans tend to love hydrocarbons far more than the democrats as far as I can tell. (I am Australian, so I don't follow US politics with a microscope level of focus.)

You are confusing direct edicts with emulating tone and phrasing.

While Trump himself did not direct the DoE to use those terms, it damn sure sounds like something he would say.  It's a way to ride on his cultural dynamic and appeal to his base.

A cynic could even suggest (granted even just tenuously) that it's a direct signaling from them (the two authors here) to Trump that they are directly on board and on brand with his message in hopes of getting greater recognition for future cabinet positions.

People in their immediate area should be able to pick up on it pretty well...
