Sonia Sotomayor took her bench in Washington Tuesday as the first Hispanic U.S. supreme court justice.
She was welcomed by her new colleagues in a brief special ceremony held at the Supreme Court.
U.S. President Barack Obama and Vice President Joe Biden were among those who attended the ceremony in which the court formally accepted her as the new member.
Sotomayor, 55, formally joined eight other justices on the bench.
Nominated by Obama, she was confirmed by the Senate in August, replacing retired justice David Souter.
