Officials say that President Obama will nominated U.S. Court of Appeals judge Sonia Sotomayor to fill David Souter's seat on the Supreme Court. Sotomayor, who grew up in a Bronx public housing project and was named to the federal bench by President George H.W. Bush, has been mentioned as a possible nominee since even before the election. The announcement will be made at 10:15 a.m.; the Caucus reports, "The president reached his decision over the long Memorial Day weekend...The president narrowed his list to four, according to people close to the selection process, including Federal Appeals Judge Diane P. Wood of Chicago, Homeland Security Secretary Janet Napolitano and Solicitor General Elena Kagan." Obama hopes to have his pick confirmed by the time Senate recesses in August. SCOTUS blog has an interesting post on a Sotomayor nomination: "For Republican Senators to come after Judge Sotomayor is not only hopeless when it comes to confirmation (something that did not deter Democrats in their attacks on Roberts and Alito) but a strategy that risks exacting a very significant political cost among Hispanics and independent voters generally."
