( - Chief Justice John Roberts will once again administer the oath of office to President Barack Obama -- first on Sunday, Jan. 20 and again for show during the public inauguration on Monday, Jan. 21.

Associate Justice Sonia Sotomayor will do the same for Vice President Joe Biden, the Presidential Inaugural Committee announced Friday.

“I will be honored to again stand on the Inaugural platform and take part in this important American tradition,” President Obama was quoted as saying in the news release. “I look forward to having Chief Justice John Roberts administer my oath of office as we gather to celebrate not just a president or vice president, but the strength and determination of the American people.”

The committee notes that President Obama is following presidential precedent in choosing the Chief Justice to swear him in.

Vice President Biden personally selected Justice Sotomayor, who will be the first Hispanic and fourth female judge to administer an oath of office. (Judge Sarah T. Hughes swore-in President Johnson in 1963; Justice Sandra Day O’Connor swore-in Vice President Dan Quayle in 1989; and Justice Ruth Bader Ginsburg swore-in Vice President Al Gore in 1997.)

"It's an incredible honor to have Associate Justice Sonia Sotomayor swear me in,” Biden said. “I believed strongly that she would make a great Justice, and it was one of the greatest pleasures of my career to be involved in her selection to the Court.  From the first time I met her, I was impressed by Justice Sotomayor’s commitment to justice and opportunity for all Americans, and she continues to exemplify those values today. Above all, I’m happy for the chance to be sworn in by a friend – and someone I know will continue to do great things.”

Historically, Inaugural Ceremonies are not held on a Sunday because the courts and other public institutions are not open. This year, as the Constitution requires, President Obama and Vice President Biden will officially be sworn in on Sunday, January 20, 2013. The ceremonial swearing-in will take place Monday on the West Front of the U.S. Capitol.

On another front, the inauguration committee has just opened its official store, selling $20 keychains, $5 magnets, and other mementos that are billed as "the perfect way to remember a historic moment."

The most expensive item is a $7,500 silver and gold medallion set, showing the profiles of Obama and Biden.
