GRAND RAPIDS (WKZO) -- Two federal air marshals are expected to be charged soon with assault after a fight outside a bar in downtown Grand Rapids.  Matthew Davids and Jon Holdsworth were in town on vacation when they allegedly got into the fight.  One man says he was kicked in the groin in the fight, and added the fight started when one of the two marshals shoved a woman and then punched a man who came to her defense.
