@foxnews: A mother in Ohio had the courage to call authorities on her 19-year-old son, blowing open the plot to attack this weekend's UFC event at The White House, David Spunt reports. Five suspects are in custody and facing charges as investigators identify 23 people as part of a potential network of plotters. The alleged plan involved using explosive-laden drones to hit buildings near the event, force a mass evacuation and steer crowds toward a pre-staged sniper team, officials say.
