It's since disappeared, for whatever reason, but yesterday on TW there was a posting of Potter's military records, supposedly obtained via a Freedom of Information request from the records center in St. Louis. It showed him being a complete fraud - an MP, reserves only, never an officer, no combat experience, no intel affiliation.
Especially since those documents disappeared, I have no idea if they were faked, or if he is fake. There seem to be a lot of claims both ways.
