FBI Director Kash Patel said Tuesday that the bureau is investigating members of a Discord chat in which Tyler Robinson, the accused shooter of Charlie Kirk, allegedly revealed his plans. 

The 22-year-old Robinson was charged with first-degree aggravated murder and felony discharge of a firearm causing serious bodily injury on Wednesday. Kirk, 31, was fatally shot on the campus of Utah Valley University last week. 

On Monday, the Washington Post reported that Robinson appeared to confess to the killing in a Discord chat room hours before he was taken into custody by the FBI. Discord is an instant messaging platform utilized by many gamers. 

“Hey guys, I have bad news for you all,” Robinson said, according to the Washington Post. “It was me at [Utah Valley University] yesterday. im sorry for all of this.”

During questioning by Sen. Josh Hawley (R-Mo.), Patel confirmed that the FBI is “investigating anyone and everyone involved in that Discord chat.”

“So what we’re doing, we’ve already done is a sort of legal process, not just on Discord, so that the information we gathered is sustained and held in an evidentiary posture that we could use in prosecution, should it be decided to do so,” Patel said. “And we’re also going to be investigating anyone and everyone involved in that Discord Chat.”

The New York Times also reported Saturday that, in another Discord chat last Thursday, the accused gunman claimed a “doppelganger” was attempting to “get me in trouble” after a user noted the similarities between Robinson and photos of the shooter that law enforcement had released. That chat consisted of roughly 20 members, according to the report. 

Patel, though, when asked by Hawley about the number of Discord users the FBI is pursuing, said “it’s a lot more” than 20. 

“We’re running them all down,” Patel said. 

The Hill has reached out to Discord for comment on the investigation. 

Patel also said investigators have conducted interviews with Robinson’s family members and members of his community. Robinson was born in St. George, Utah, and lived in Washington, Utah, at the time of the shooting. 

Utah Gov. Spencer Cox (R) told NBC News on Sunday that Robinson “came from a conservative household” but had different beliefs than his family. 

“In terms of what we do [from] an interrogation perspective, we go and reach out to the family and community immediately, and we’ve conducted those investigations and interrogations with local law enforcement,” Patel noted in his testimony.

“And we’re continuing to do that, because those closest to the suspect are going to hopefully know the most about the suspect and his beliefs and his ideology.”
