Bill Clinton accepted a $225,000 speaking fee from the nonprofit Washington Hospital Center smack in the middle of two big rounds of layoffs in 2012. Washington Hospital Center officials confirmed their payment to Mr. Clinton Thursday. So Young Park, a hospital spokeswoman, said Mr. Clinton spoke at the annual Cardiovascular Research Technologies conference, where he talked about health care reform and his own battle against heart disease. She said the meeting generates ?net revenue? for the hospital but declined to provide any details about how much money the conference raised or what portion of that revenue officials believed came from people coming to hear Mr. Clinton?s speech.
