Why Did Michael Johnson Leave "Celebrity Apprentice"

Yesterday Olympic Gold Medal winner Michael Johnson unexpectedly left the 2010 Celebrity Apprentice show due to a private family matter, although many simply says that he left because he was fired. Donald Trump has kept quiet on the matter and refused to speak why or how Michael Johnson leaving the Apprentice will affect the outcome of the show. Since Johnson left the Apprentice, only 3 men remain as contenders.
