The president re-takes the oath of office.
Why did President Obama take the presidential oath of office again?
Chief Justice John Roberts and Obama decided to repeat the time-honored tradition Wednesday night in the White House's Map Room out of an "abundance of caution," a presidential rep tells the Associated Press.
Roberts' slight misreading of the oath during Tuesday's inauguration caused the president to repeat the words a bit differently than they appear in the Constitution, says the AP.
