The President intends nominating Elena Kagan, the current Solicitor General of the United States, as the next (and 112th) justice of the United States Supreme Court, according to the Washington Post.
In replacing Justice John Paul Stevens, Obama would also be breaking with tradition. Every other member of the court is a former federal appeals court judge, and Kagan has never served in the judiciary. The last time a non-judge was appointed was 1972, when President Richard M. Nixon nominated William H. Rehnquist and Lewis Powell in the same year.
