So if Trump never takes the oath, for the whole four years, who is President? Either the President elect has to take the oath, or he doesn't. I think he has to. Until he does, whether the interval is 30 seconds, or 48 months, we do have an acting President. And for 30 second or so this Friday, it will be John Kerry.
There’s a theory out there that Obama never took the real oath of office.
That the “So help me God.” was not said correctly or soemthing.
