FBI Deputy Director Dan Bongino said Monday that investigators are probing whether Charlie Kirk’s alleged assassin acted alone or as part of a broader plot, while also revealing troubling signs that the suspect had been “taken over” by ideology leading up to the shooting.

Bongino told Fox News’ “America’s Newsroom” that although one suspect is in custody, the Bureau is “looking into” possible accomplices. 

“If this was a larger effort, if there was any aiding and abetting, whether it be financial or someone who knew the specifics of it and failed to report that, we’re looking into that,” he told Bill Hemmer Monday. “There’s not going to be a stone left unturned.”

While stressing that the case is still developing, Bongino said the motive is clear: “It’s fairly obvious this was an ideologically motivated attack.” 

“Charlie Kirk is a conservative commentator who sadly and tragically gave his life underneath a sign asking people to challenge his ideas, the very essence of our constitutional republic,” he said.

Bongino, who described Kirk as a close personal friend, added that the FBI’s rapid response should reassure the public.

“We got our guy in 33 hours. Next time, when there’s a crisis, we’ll look at what we can do well and what we can do better,” he said. “We can do better than that.”
