National Security Adviser Tom Donilon is stepping down after four years on the job and will be replaced by United Nations Ambassador Susan Rice — the latest in a series of defiant appointments likely to rile the GOP and fire up the Democratic base.
Obama will nominate Samantha Power, an anti-genocide activist and author who won a Pulitzer Prize for “A Problem from Hell: America and the Age of Genocide,” as Rice’s replacement.
The appointments of Rice and Power not only represent the ascension of women to top roles on Obama’s national security team, but the rise of two officials who have made human rights a priority — at a time when the U.S. faces an agonizing decisions over Syria where President Bashar al-Assad has killed tens of thousands of civlilans.
