Is there a risk they could do it at 12:01 am on January 20 and claim that he is now President, so he can start giving orders?

Depends where we are, if the Mil has seen the fraud evidence that they collected, which seems likely, then this show is over.

[TrueFact]

Constitution specifies non on the 20th of January as the end of a president’s term. Midnight on 20th would be invalid.
