An anonymous source told Dan Rather that Venezuelan President Hugo Chavez was suffering from metastatic rhabdomyosarcoma, an aggressive cancer that has entered its "end stage."
Rather said on Wednesday that the information and quote came "from a highly respected source close to Chavez and who is in a position to know his medical condition and history," according to HDNet. However, he acknowledge that he had only one source on this information.
Rather's source said the prognosis for Chavez, who is running for reelection, was dire and he was not expected to live "more than a couple of months at most."
