The announcement hasn't worked through official legal channels, but Anthropic is taking it seriously. The official channel will be a written explanation to Congress, and could be classified.

Hegseth objected to guardrails being "woke". Something about "curly haired" almost-men telling him how he can use his "war fighters".

I speculate that Trump and Hegseth were both late to the realization that AI could unwind, for example, the next Panama Papers, and are doing this to try to demonstrate power to the industry. Musk tried to explain all this, but they actually encountered him as "autistic". This all looks like a disjointed conversation because we can see slightly more of the future than them.
