Once an individual completes the Oath, he (or she) is President of the United States, under Art. II, s. 1 and the 20th Amendment. It’s not a bullshit theory. It says so in plain English. Enforcing it is another story.
Art II: 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."
20th Amendment: The terms of the President and the Vice President shall end at noon on the 20th day of January, and the terms of Senators and Representatives at noon on the 3d day of January, of the years in which such terms would have ended if this article had not been ratified; and the terms of their successors shall then begin.
The Chief Justice said to Biden: “Congratulations, Mr. President” after the oath was completed. It was before noon at that point. The oath was void.
