"The group includes U.S. Solicitor General Elena Kagan and federal appellate judges Diane Wood and Merrick Garland, the person said, speaking on the condition of anonymity. Stevens, who will turn 90 on April 20, told the New York Times in an April 2 interview that he will decide soon whether he will step down. 'The president and the Senate need plenty of time to fill a vacancy,' Stevens told the newspaper. Stevens hasn’t communicated his intentions to the White House one way or another, according the person familiar with the deliberations.
