USDA and the administration are catching flak because of this:
The Agriculture Department last week began mandating that millions of boxes of surplus food for needy families include a letter from President Donald Trump claiming credit for the program.
I'm trying but failing to remember somewhat of a parallel. Secretary Bergland signed a letter which we sent out to farmers, perhaps to all active producers associated with a farm. This was, I think, in 1980, an election year. The subject was something related to crop insurance. I don't remember whether it was base on legislation or a policy decision, perhaps an expansion of the insurance program.. I do remember ASCS had been running a test of selling crop insurance, because Roy Cozart, who became DASCO when the Reagan administration came in, was working on putting FCIC directives into the ASCS system. That test was a failure.
IIRC we career bureaucrats, and possibly Roy, who was career but with political pull, raised an eyebrow on it. The differences between then and now: Jimmy Carter didn't sign the letter and I remember the content as being more informative and less propagandistic than the current letter.
