i can imagine this being an area where the separation of powers actually rears its head.
the US government is all about asset forfeiture. the courts allow it, the lawmakers codify it, and the executive does it. they all work together with the eager efficiency of desperate lovers.
but built into that is the assurance that each branch gets their taste of that sweet plunder. not an equal split, but none is left out.
unless im misunderstanding the EO, this is like the executive saying "no, it's all mine, you can't even ask how much there is."
