WHITE HOUSE - John Roberts has been sworn in as chief justice by one of the men he'll be sitting alongside on Monday.
Justice John Paul Stevens administered the oath of office to the new chief justice in a White House ceremony, with President Bush looking on and Roberts' wife holding the Bible.
The other Supreme Court justices sat in the East Room for what the president called "a very meaningful event in the life" of the nation.
Bush called Roberts "an exceptional new leader" and said the swearing-in marked "a day of renewal" for the high court. He says all Americans can be sure Roberts will be "a faithful guardian of the constitution."
Roberts took the podium after the ceremony and pledged to do the best job he can, and to pass on a Constitution that is as "strong" and "vibrant" as the one being passed on by the late Chief Justice William Rehnquist.
The Senate approved Roberts' nomination earlier today, 78-to-22.
