Mudslinging Obama Adviser Steps Down

One of Barack Obama's top advisers resigned today, hours after the publication of an interview in which she called Hillary Clinton a "monster." Samantha Power apologized to both candidates, but her remark contrasted sharply with the campaign's take-the-high-road strategy, Reuters reports. "She is a monster, too—that is off the record—she is stooping to anything," Power told the Scotsman.

The foreign-policy expert—a Harvard professor and Pulitzer Prize winner for her book about genocide—made several other unflattering comments about Clinton, saying she looked "desperate" and that "the amount of deceit she has put forward is really unattractive." "Senator Obama decries such characterizations which have no place in this campaign," a spokesman said. (More Samantha Power stories.)
