Elena Kagan has been sworn in as the newest justice in the US Supreme Court.
She is President Barack Obama's second appointment to the US's most powerful court and only the fourth woman to serve on the nine-member panel.
The 50-year-old becomes the youngest serving Supreme Court judge. She will serve alongside President Obama's first appointment, Sonia Sotomayor.
She is thought unlikely to alter the balance of the court as she replaces liberal justice John Paul Stevens.
Ms Kagan swore to "faithfully and impartially" uphold the law for all Americans.
She will formally join the court on 1 October, just before the judges return to the bench for a new session after their summer recess.
