A few things you may not know about the inauguration:
- According to the Constitution, the changeover to the presidency happens at 12:01pm on January 20. It doesn't matter that Obama took the oath of office a few minutes late; he became president at 12:01. At that point, the Secret Service agent who shadows the president switches from one to the other.
- "So help me God" is not part of the Constitutional oath of office, and it wasn't said until the 1885 inaugural of Chester A. Arthur. There's currently a court case arguing that the chief justice and president do something unconstitutional in taking the oath of office.
- You weren't invited to the luncheon in Statuary Hall.
