And thus a nickname is born.
Apparently Chief Justice John Roberts has been dubbed "Oaf of Office" in the US Media for his role in Obama's Oath of Office.
Chester A Arthur and Calvin Coolidge also had to repeat the oath.
Chester A Arthur swore the oath at home with a New York Supreme Court Judge John R. Brady, but then repeated it when he arrived in Washington D.C.(as he was ascending from the Vice-Presidency to the Presidency after the death of President Garfield)
Coolidge also ascended from the Vice Presidency after his Father administered the initial Oath of Office upon receipt of the news via messenger that President Harding had died. He re-took the Oath of Office upon his return to Washington D.C. the following day.
