Obama said Sotomayor has more experience as a judge than any current member of the high court had when nominated, adding she has earned the "respect of colleagues on the bench, the admiration of many lawyers who argue cases in her court and the adoration of her clerks, who look to her as a mentor."

Standing next to Obama at the White House, Sotomayor recalled a childhood spent in a housing project in the Bronx as well as her upper-echelon legal career: "I strive never to forget the real world consequences of my decisions on individuals, businesses and government."

Barring the unexpected, Senate confirmation seems likely, given the large Democratic majority. If approved, she would join Justice Ruth Bader Ginsburg as the second woman on the current court, the third in history. She would succeed retiring Justice David Souter.

Senate Majority Leader Harry Reid, D-Nev., issued a statement saying he looked forward "to working with both Democrats and Republicans on the Judiciary Committee to confirm Judge Sotomayor as the first Hispanic and the third woman to sit on the court."
