This makes zero sense logically.
If they allow Biden to swear in within two minutes of that he can declare the emergency over and thus FEMA looses all power.
If they allow him to swear in and they ignore his stand down orders, then it is a full blown military coup.
Lastly, many military members understand the chain of command of the CiC on down. Why exactly would they allow Biden to become CiC? Military members may have a hard time following orders if they conflict with the CiC.
If Trump transfers power to military to clean things up and Biden is arrested before hand, it no longer appears to be a coup and is instead a military operation.
