White House officials declined to say who Mr. Obama’s choices will be ahead of an announcement that could come this week, but leading contenders for the spots appear to include Cornelia T. L. Pillard, a law professor at the Georgetown University Law Center; David C. Frederick, who often represents consumers and investors at the Supreme Court; and Patricia Ann Millett, a veteran appeals lawyer in Washington. All three are experienced lawyers who would be unlikely to generate controversy individually.

Several legal advocates who have been in communication with the West Wing said officials had repeatedly discussed those names in recent months.
