Federal investigators claim five men arrested for their involvement in the riot on Capitol Hill were members of a militia group that held beliefs aligned with Three Percenters.

The group includes people linked to the Oath Keepers militia group who have been indicted on charges that they planned and coordinated with one another in the attack. Investigators said Kenneth Harrelson is a member of the Oath Keepers and attended dozens of planning calls with other members before they stormed the U.S. Capitol on Jan. 6. The Oath Keepers were among several militia and extremist groups, such as the Proud Boys, that took part in the Jan. 6 Capitol riot. The SPLC also said Rhodes worked on Ron Paul’s 2008 presidential campaign prior to starting the Oath Keepers. The Oath Keepers claim tens of thousands of members on its rolls but, according to the ADL, that is unlikely, but they may have a couple of thousand members.
