Questions are being asked about what has happened to almost half a billion dollars of aid money donated to the Red Cross to help Haiti after its catastrophic 2010 earthquake. Politicians in the US and Haiti - including the former Prime Minister of Haiti - are calling for an inquiry, following a report by investigative journalists alleging that the Red Cross provided little actual help for those left homeless, and delivered only a portion of the money it raised to Haitians. The aid organization had pledged to give 91 cents of every dollar. Justin Elliot is an investigative reporter and co-author of the report published by ProPublica and NPR.
