Co-worker sent in a trust, was returned saying all trustees need prints and CLEO signoff.
I think there is some sort of misunderstanding about the letter or that some details are wrong. Title 26 Chapter 53 paragraph 5812 says;
So a natural person must use photos and fingerprints while trusts use whatever the Attorney General wants, including photos and fingerprints.(a) Application. A firearm shall not be transferred unless ....(3) the transferee is identified in the application form in such manner as the Secretary may by regulations prescribe, except that, if such person is an individual, the identification must include his fingerprints and his photograph;
Title 27 CFR Chapter II only requires that a natural person who is not an FFL obtain the CLEO signature. I don't think any executive order or whim of the AG is going to require a trustee to obtain a CLEO signature.
