A 2025 ProPublica investigation examines internal records John Williams obtained while gaining access to AP3 and Oath Keepers leadership. He was an independent infiltrator, not a law-enforcement operative, and the reporter cross-checked documents, recordings, and numerous interviews. Related earlier AP3 coverage uses extensive internal messages to trace armed activity and attempts to build police relationships, providing organizational context. However, personal motives and every statement were not verified to the same degree, and historical findings cannot establish the current activity of entire organizations.
