I don’t know why they need to have an inauguration ceremony with outsiders in attendance. He should take the Oath ASAP (the Constitution requires only that he take the oath before he assumes office on the 20th. In fact, he might not technically have to take the oath at all since he took it 8 years ago.)
So he should take the oath in private, have it recorded with a time stamp, and he automatically assumes office at noon on the 20th. There’s no need to have the inauguration ceremony at all on the 20th where there is any risk to him.
WOULD BE GREAT IT HE TOOK THE OATH AT 12:01 AM on the 20th AT MAR A LAGO WITH JUSTICE THOMAS...
ONLY FAMILY & trusted others in attendance
