It's interesting that Musk is sending this, probably personally and likely without getting specific approval from Trump before sending it, and the agencies are responding to ignore it in what is clearly a direct response to Musk.
Musk acts. Many cabinet departments act in response. Meanwhile, Trump is a passive non-participant in his own administration.
(To say nothing of Congress thus far.)
Thanks for posting this, since it also didn't get much attention in the media.
Even though these actions are almost certainly illegal, I'm at least somewhat relieved that Trump is (mostly?) following injunctions and not brazenly defying the judicial branch. Defying the Supreme Court would be crossing the Rubicon, IMO.
