Yesterday President Obama nominated Solicitor General Elena Kagan to replace retiring Justice John Paul Stevens on the Supreme Court. Article II of the United States Constitution requires the President to submit nominations to the Senate for advice and consent. Since 1789, presidents have submitted 159 nominations for the Court, 123 of which were confirmed.
More information about Supreme Court nominations can be found on the Senate Judiciary Committee website and the Library of Congress website. The transcripts of Supreme Court nomination hearings from 1971 – present are available at the GPO Access website. University of Michigan Law Library also has set up a timely website on Kagan. For more information and updates of the development, try the special pages posted by New York Times and Washington Post.
