Portsmouth - The Clinton Foundation said on Thursday that Bill, Hillary and Chelsea Clinton have raised at least $12m to support the family's philanthropy since 2002 by delivering paid speeches to an assortment of corporations, universities and foreign entities.The speeches may have brought in as much as $26.4m to the foundation, which released a list of nearly 100 speeches and a broad range of the fees the Clintons received for delivering them.The fees benefited the Clinton Foundation, the global charity the former president started after he left the White House.
