Supreme Court justices, in business clothing, have just entered the U.S. Capitol, where they will, by tradition, head to the court's old chambers to don their robes for the inauguration ceremony. Among them were Justice Sonia Sotomayor, who has had a busy weekend. She swore in Vice President Joe Biden early Sunday morning -- timing apparently dictated in part by the fact that Sotomayor had a book signing scheduled in New York City later in the day. She returned in time for today's ceremonial swearing-in of Biden. Chief Justice John Roberts Jr. will swear in President Barack Obama, as he did yesterday just before noon.
The justices, also by longstanding tradition, began their day with breakfast in the court's east conference room. After the ceremony they will join others for lunch with the president in Statuary Hall at the Capitol. The justices have been supplied with hand warmers and ear muffs if needed. Whether or not they will wear the black skullcaps that justices have worn from time to time at inaugurals remains to be seen. More on that later.
