From Jake Tapper, George Stephanopoulos, and Martha Raddatz:
ABC News has learned that Dr. Susan Rice has emerged as the leading candidate to be President-elect Obama's nominee as U.S. Ambassador to the United Nations.
Neither Dr. Rice nor the Obama Transition Team had any comment. The usual caveats apply -- nothing is yet a done deal, nothing has been officially offered or accepted, national security team announcements will not come until after Thanksgiving.
Dr. Rice, a member of President Bill Clinton's National Security Council and a former Assistant Secretary of State for African Affairs, was involved in President-elect Obama's campaign as a senior foreign policy adviser.
The former Rhodes Scholar in 2000 received the National Security Council's Samuel Nelson Drew Memorial Award for distinguished contributions to the formation of peaceful, cooperative relationships between nations, and U.S. security policy for global peace.
