WASHINGTON -- Shaking up his national security team, President Barack Obama tapped diplomat Susan Rice as his national security adviser, defying Republicans who have vigorously criticized her faulty explanation about the attack on Americans in Benghazi, Libya.
"Susan is the consummate public servant -- a patriot who puts her country first," Obama said while announcing Rice's appointment Wednesday during a Rose Garden ceremony.
Rice will take over the top national security post from Tom Donilon, who is resigning after four years in the White House. Obama lauded the 58-year-old Donilon for having "shaped every single national security policy of my presidency," including the renewed U.S. focus on ties with Asia.
The president also announced the nomination of former White House aide Samantha Power to replace Rice as U.S. ambassador to the United Nations. Power is a human rights advocate and expert on genocide.
It's unclear whether the changes signal a significant shift in Obama's foreign policy, particularly in Syria, where the U.S. is being pressured to act against President Bashar Assad.
Power is seen as a proponent of American intervention on humanitarian grounds and Rice backed greater U.S. involvement in Libya, though administration officials have made clear they don't draw direct comparisons between the current situation in Syria and the 2011 push to oust Libyan leader Moammar Gadhafi. In that situation, the U.S. Britain and France maintained a no-fly zone to allow rebels to fight back against Gadhafi.
For Rice -- a longtime Obama ally and close confidante of the president -- the appointment is a bit of redemption after she was forced to withdraw from consideration as Obama's second-term secretary of State amid criticism of her handling of the Benghazi attacks. Rice said at the time that she did not want her confirmation hearing to become a distraction for the White House. The national security post does not require Senate confirmation.
Neither Obama nor Rice mentioned the Benghazi controversy during Wednesday's ceremony. Rice said she looked forward to working with lawmakers from both parties "to protect the United States, advance our global leadership and promote the values Americans hold dear."
