Walmart has shared that managers misused $20,000 of a Christmas donation from a foundation associated with Chicago Bears linebacker Khalil Mack. Mack's foundation made the $80,000 donation last month to a location in Fort Pierce, Florida, where the star athlete was born and raised. The donation went towards 350 layaway accounts that totaled $60,000. The remaining funds reportedly went to employees in a decision made by the store's management.
