FBI Deputy Director Dan Bongino has said investigators are probing whether a “network of people” around the suspect accused of assassinating Charlie Kirk may have known about the attack in advance.Kirk, 31, was fatally shot while speaking at Utah Valley University on September 10. Tyler James Robinson, 22, of Washington, Utah, was arrested on suspicion of aggravated murder and other felony offenses.Bongino told The Megyn Kelly Show on Monday that it was “up in the air” how many people lived with Robinson, besides his partner Lance Twiggs.”We have the suspect in this case and then we have Lance. How many people they associated with and how many in fact lived or resided there? It’s up in the air,” he said.”However, there is apparently a network of people… given his network of friends and associates, what was the level of foreknowledge about this attack? Did they know something and refuse to say something? Did they know something and think it was a joke?”Utah Governor Spencer Cox previously said that Twiggs had “been very cooperative” with law enforcement and “had no idea that this was happening.”This is a developing story.
