Irish advisor to Obama steps down [video 2min]

A foreign policy advisor to Democratic presidential candidate Barack Obama has resigned from his campaign and apologised, after calling rival Hillary Clinton a 'monster'. Samantha Power, a Harvard professor and journalist, was born in Ireland, where she is currently touring. She said she regretted making the remark. Ms Power said it was an off-the-record comment to the Scotsman newspaper, but the paper's editor said it had clearly been done on the record. During a visit to Belfast, where she gave a lecture on March 7th at Queen's University, Professor Power told RTÉ News she regretted her comment, which she described as 'very stupid'. She said it was 100% thoroughly her fault.
