Christian Walker is the 23 year-old son football legend Herschel Walker. Donald Trump supports the Heisman Trophy-winning candidate for the U.S. Senate in Georgia. When reports this week claimed that the older Walker paid for a former girlfriend’s abortion, Christian went ballistic against his father. Christian’s mom, Cindy Grossman, has accused her ex-husband of violent behavior, claiming he once pointed a gun at her head. Herschel Walker said he doesn’t recall the incident.
