Considering he is quite possibly not even Constitutionally elligible by birth, it’s a very small matter in comparison.
However, oath or not, he’s the President as of noon yesterday. Who was the Pres so drunk that he couldnt finish the oath thus ushering in that law?
The president-elect becomes President at noon, but until the oath is taken, he cannot execute the office:
Before he enter on the Execution of his Office, he shall take the following Oath or Affirmation: "I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States."
I have no idea. It was also kind of weird that the oath wasn't done until after noon. If I remember correctly isn't the oath usually done just before noon so that you have pledged before you actually become President?
