Ah, so you acknowledge that when you stated that it WASN'T Trump but NOAA that's defunding the observatory, you were misstating the facts, i.e. you were being a dingbat.
The Trumpbat instructs, others implement, who's responsible?
Ding, ding, ding!
And, poor delusion dingbat: we've established that your supreme overlord Trump doesn't do everything himself (because he's not competent, apart from anything else), so what REALLY happens is that Lutnick proposes, Trump agrees, and then Senate rubber stamps. Possibly Lutnick is "guided" by Trump's minders (Miller?) to propose an individual that's been suitably obsequious or butt-kissy, but that's a distinction with no real difference.
And no, I wouldn't be surprised about Grimm. But I'm (not really) surprised why you think the Chief of Staff of NOAA is relevant to this issue? Yes, Ms Grimm came to NOAA from WWF. But she's the ACTING head, until the Senate confirms the nominee (and you jolly cleverly outlined the process, smart boy!) and in the meantime she's just the caretaker.
The nominee is Dr Neil Jacobs, who's principal claims to fame include trying to pressure meteorologists to support the Orange Overlord's stupidity about the path of a storm (Hurricane Dorian, as it happens) and the notorious Sharpie incident, as well as other examples of dumbness (see e.g. https://blog.ucs.org/rachel-cleetus/we-watched-neil-jacobs-confirmation-hearing-for-noaa-administrator-and-are-concerned-about-what-we-heard/).
