Have not seen any notables regarding use of AF2 callsign for Kamala Harris, but absence of AF1 callsign for Joe Biden. Seemed to me that the prevailing theory on Biden was that the military did not recognize him as legitimate. Thus he had a fake inauguration and no recognition as pres with AF1 callsign. Does this mean they recognize Harris as legit? Or, is it recognition that the sworn Biden is not the real Joe Biden. If not, where is Joe?
