Capitol rioter in ‘Camp Auschwitz’ sweatshirt identified

(NEXSTAR) — A man who stormed the Capitol Wednesday wearing a sweatshirt with the words “Camp Auschwitz” on it has been identified. According to three sources who spoke to CNN, the man is Robert Keith Packer of Virginia.

Auschwitz refers to a complex of more than 40 concentration and extermination camps run by the Nazis during the Holocaust.

The bottom of Packer’s sweatshirt reads “Work Brings Freedom,” likely in reference to the German phrase “Arbeit macht frei,” which is emblazoned on the iron gates of Auschwitz.

Per the three anonymous sources that spoke to CNN, Packer previously worked as a welder and pipe-fitter and was a “long-time extremist who has had run-ins with the law.”

“He’s been always extreme and very vocal about his beliefs,” the source told CNN.

On Twitter Wednesday, the FBI announced it was seeking information “that will assist in identifying individuals who are actively instigating violence in Washington, D.C.”

The agency is urging people who saw unlawful activity during the violent protests to submit information to them. The FBI has provided an online tips form.

“If you have witnessed unlawful violent actions, we urge you to submit any information, photos, or videos that could be relevant to the #FBI at http://fbi.gov/USCapitol.” 

The FBI also said people may call ‪(800) CALL-FBI to report tips and/or information related to the investigation.
