Obama adviser says Clinton "a monster"

Now tell us something we don't know.

LONDON - An adviser to Democratic presidential candidate Barack Obama apologized Friday for telling a Scottish newspaper that rival Hillary Rodham Clinton is "a monster."

Samantha Power, a foreign policy adviser to Obama's presidential campaign and Pulitzer Prize winner, was quoted in remarks she later attempted to retract as saying in The Scotsman newspaper that Clinton was stooping to low tactics to recover ground in the race to win the party's presidential nomination.

The Harvard professor is quoted as telling the newspaper Obama's team had been disappointed with Clinton's campaign win in Ohio on Tuesday.
