She can do what she wants...except...violate her agreement to protect classified information.
Not true.
If she is excepting pay from the DoD (e.g. a retirement check) then she is still accountable to the UCMJ, which includes the prohibition against indicating official DoD (she's in uniform) support, or rejection, of a political candidate.
Further, as a retiree, she would be entitled to wear her uniform at appropriate functions...this does NOT include bashing a political candidate. She risks losing pay and allowances if not other punitive measures.
Outside of uniform and without indications the DoD is supporting her.....entirely different story.
Prove it. I’m retired and never heard such a thing. Also, if you recall, Scoyus rejected the stolen valor laws. People can dress as they wish.
I call BS. Prove me wrong and post the UCMJ regulations. I will apologize if I am wrong but I don’t think I am.
