FLINT - Filmmaker and Davison native Michael Moore spoke before a fired-up crowd in downtown Flint today about the water crisis. In his speech he asked that President Barack Obama visit Flint, when the president is at the North American International Auto Show next week. Moore said that Obama needs to come to Flint before it becomes the president's version of Katrina, conjuring images of when President Bush flew over, but initially did not go to, New Orleans after Hurricane Katrina stuck the city.
