With President Barack Obama and Vice President Joe Biden watching, new Supreme Court Justice Sonia Sotomayor formally took her seat on the Court Tuesday afternoon as Chief Justice John Roberts Jr. wished her a “long and happy career in our common calling.” A beaming Sotomayor, joined in the courtroom by family, friends and a star-studded list of legal heavyweights, said, “Thank you” and the brief but historic investiture ceremony was over.

Minutes later, having shed their black judicial robes, Sotomayor and Roberts walked out of the front door of the Court in business clothes and down its marble stairs to give press photographers one of their last chances to snap her picture before she takes up the work of the mainly camera-shy institution.
