Tom Donilon To Resign as National Security Adviser, Susan Rice To Take Over

Latest Obama administration shakeup

WASHINGTON — In a major shakeup of President Obama's foreign-policy inner circle, Tom Donilon, the national security adviser, is resigning and will be replaced by Susan E. Rice, the American ambassador to the United Nations, White House officials said on Tuesday.

The appointment, which Mr. Obama plans to make on Wednesday afternoon, puts Ms. Rice, 48, an outspoken diplomat and a close political ally, at the heart of the administration's foreign-policy apparatus.

It is also a defiant gesture to Republicans who harshly criticized Ms. Rice for presenting an erroneous account of the deadly attacks on the American mission in Benghazi, Libya. The post of national security adviser, while powerful, does not require Senate confirmation.
