Out of what is claimed as "an abundance of caution," president Barack Obama has taken the oath of office for a second time on Wednesday night, January 21. The oath retake, taking place in the Map Room of the White House in Washington, DC, lasted for about 25 seconds. The event was closed to TV camera crews and news photographers. Only a few of Obama's closest aides were there, along with a White House photographer.
Concerning what prompts the oath retake, it is reported that Chief Justice John Roberts, who first administered the oath to Obama on Tuesday, January 20 on the steps of the U.S. Capitol, accidentally switched the word order when he administered the oath. He said "I will execute the office of president to the United States faithfully," instead of, "I will faithfully execute the office of president of the United States," Reuters reports.
