There were witnesses as prescribed by law when LBJ took the oath of office.
United States Code, Title 5, I believe, stipulates the requirements for administering an oath.
Obama couldn’t take the oath all by himself. So the scenario you provide is unrealistic.
Thanks for the reference. I’ll look that up after I get done playing for a funeral this morning.
What if the only witness to LBJ’s Presidential oath of office refused to say whether a lawful oath was in fact, taken, and the video footage the witness says she took was not allowed to be shown to anybody because LBJ said the video made him look fat?
At that point would LBJ have been LEGALLY able to act as CINC? Who would determine that, and what procedure would they use to determine that?
