Obama Adviser Resigns

Samantha Power, a foreign policy adviser to Barack Obama's campaign, has resigned, CBS News' Maria Gavrilovic reports. Power, who was not a paid member of the campaign came under fire from Hillary Clinton's campaign after she called the New York Senator a "monster" in an interview with the Scotsman newspaper.

In a statement released from the campaign, Power said: "With deep regret, I am resigning from my role as an advisor the Obama campaign effective today. Last Monday, I made inexcusable remarks that are at marked variance from my oft-stated admiration for Senator Clinton and from the spirit, tenor, and purpose of the Obama campaign. And I extend my deepest apologies to Senator Clinton, Senator Obama, and the remarkable team I have worked with over these long 14 months." Power is a Harvard professor and Pulitzer Prize winner.
