After months of sledging fellow Democratic candidate Barack Obama, Hillary Clinton has drawn a bead on a slightly more unusual target - her daughter's profession.

During a scheduled economic discussion at a restaurant in the US state of Ohio on Tuesday, Senator Clinton rubbished wealthy investment bankers and hedge fund managers, saying they they weren't doing "real work".

Senator Clinton's daughter, Chelsea, works for New York-based hedge fund Avenue Capital Group and previously held a post with international management consulting group, McKinsey and Company.
