WASHINGTON (AP) -- Chief Justice John Roberts will swear in President Barack Obama for a second term later this month.

The Presidential Inaugural Committee says Roberts will administer the oath of office at the White House on Jan. 20, as required under the Constitution. Since that's a Sunday, Roberts will also do the swearing-in at the public inaugural ceremony Jan. 21 at the U.S. Capitol.

Supreme Court Justice Sonia Sotomayor (SOHN'-ya soh-toh-my-YOR') will swear in Vice President Joe Biden.

Obama followed tradition in choosing the chief justice to swear him in. Biden chose Sotomayor, who will be the first Hispanic judge to administer the oath.
