It must have been fairly recent the hearing deficiency started if he actually is using one and not a microphone. In December last year, NPR did a medical report on him and hearing was not an issue.
So if he is found to be using one, it should be challenged, or denied before he gets to the podium and proof of needing it required. Otherwise, he is being prompted illegally and not being forced to rely on his memory which is the entire intent of the debate,thinking on your feet like he would have to when face to face with other country’s leaders. Foul!
