WASHINGTON — President Barack Obama’s private swearing-in will be a brief, sparsely attended ceremony in the Blue Room of the White House.

White House spokesman Jay Carney says Supreme Court Chief Justice John Roberts will administer the oath of office on Sunday just before noon, the time required by the Constitution. Obama’s family will attend along with a few reporters, and Obama isn’t expected to make a speech.

The Constitution requires that the president be sworn in on Jan. 20, but since that falls on a Sunday this year, Obama will have two ceremonies: one on Sunday and a larger, public ceremony on Monday, followed by a parade and inaugural balls.

Officials expect 600,000 to 800,000 people to crowd the National Mall for the public ceremony in front of the U.S. Capitol.
