You, or someone you know, may have received an e-mail from the "Department of Government Efficiency" requiring a response listing what you did last week, If so, and if any portion of the job requires access to or working with confidential personal or government information, I recommend this response:
During the week beginning {date}, 2025, I [REDACTED ON NATIONAL SECURITY GROUNDS, SEE E.O. 13526 (2009) AND 13556 (2010), BOTH ORDERS AVAILABLE FOR INSPECTION AT THE NATIONAL ARCHIVES].
The e-mails are being sent by persons/parties via a system not authorized to contain classified information… and mere fiat granting a security clearance does not either magically authorize use of that system, or give the identified recipient a need to know that information (including sufficient detail allowing a hostile party to know which programs are/were active during that period), or provide any assurances that the identified recipient is the only one who will actually see that response. If there's one subject that is inherently and laughably "inefficient" in a market economy, it's the protection of confidential data — and, therefore, someone working for a Department of Efficiency has no need to know about it.
Bonus: Referring to the National Archives as an authoritative source is also the appropriate response to weaponization of the job status of individuals at the National Archives. But I'm mean that way.
