This is the kind of stuff that happens whether a (D) or (R) is in office. I don't really believe in a "deep state" in the way that I think a cabal of weirdos get together to sacrifice goats and twiddle their moustaches, but this is the closest thing there is to a deep state. The Eric Princes of the world, the CIA, and so on are the actual project that this country is carrying out. It's been a generational project, and the politicians we get to see are begging for table scraps from the people that actually get the bag.
The phrase was originally coined to refer to all the career bureaucrats and functionaries that persist through administration after administration due to being "apolitical", actually materially enacting policies or serving as consultants and sources of information for formal leaders. So yes, that is literally what the "deep state" is and what it meant before it got appropriated and warped by weirdo reactionaries who needed a new word for "illuminati" after that got too commonly recognized as nonsense.
