Barack Obama Takes Oath of Office for Second Term

Remember that thou art mortal

Barack Hussein Obama officially began his second term as the nation's 44th president Sunday, taking the oath of office in a low-key ceremony at the White House.

Chief Justice John G. Roberts administered the oath, and the two will repeat the process again Monday in a public celebration at the Capitol. The Constitution mandates that presidential terms begin on Jan. 20, and it is traditional when the day falls on a Sunday that the public ceremony take place the next day.
