These firings don’t appear to be unlawful or abusive. They’re sloppy. But he has the power to fire them.

> The removal procedure for presidentially appointed IGs is found in Title 5, Section 403(b), which reads in part An Inspector General may be removed from office by the President. If an Inspector General is removed from office or is transferred to another position or location within an establishment, the President shall communicate in writing the substantive rationale, including detailed and case-specific reasons for any such removal or transfer to both Houses of Congress (including the appropriate congressional committees), not later than 30 days before the removal or transfer. Nothing in this subsection shall prohibit a personnel action otherwise authorized by law, other than transfer or removal.

So it's illegal because he didn't notify Congress in advance. That statute was enacted in 2022 specifically to prevent abuses of power such as this.

I can't see any judge agreeing with this. The notice requirement is separate from the removal. "If an Inspector General is remove from office..." the President has to do X 30 days in advance. It's a bit convoluted to argue that if the second part isn't done, the first part is invalid. The breach is in failure to notice. That can be cured by noticing.

This is boy who cried wolf crap. The firings are unprecedented but totally legal. The breach was in forgetting to tweet some Congressmen. If we go Defcon 1 over paperwork fuckups, there's nowhere left to go when he does something that's substantively illegal.
