Obama's aide steps down after calling Hillary a 'monster'

Chicago: An aide to Democratic candidate Barack Obama, Samantha Power, stepped down from the campaign on Friday amid uproar over a comment she made to a British newspaper referring to Democratic rival Hillary Clinton as a "monster."

"She made the decision to resign and we accepted it," said Robert Gibbs, Obama's communications director. Power had been an aide to Obama in his Senate office before signing on to advise his presidential campaign 14 months ago.
