Oath Keepers

Mark Grods pleaded guilty to conspiracy and obstruction of an official proceeding. The 54-year-old Alabama man has also agreed to cooperate with investigators.

The conspiracy case involving the Oath Keepers extremist group is one of the most closely watched of those related to the insurrection at the U.S. Capitol.

The Justice Department has secured its first guilty plea in the Jan. 6 U.S. Capitol attack investigation. A founding member of an anti-government militia group has pleaded guilty on two counts.

Jon Schaffer pleaded guilty to two charges — obstructing an official proceeding and entering restricted grounds with a dangerous weapon. He has agreed to cooperate fully with investigators.

Stewart Rhodes founded the militia in 2009. Now it's one of the largest extremist anti-government groups in the country, and a focus of the investigation into the Jan. 6 attack on the U.S. Capitol.

The Oath Keepers are a far-right militia group. Court documents indicate Stewart Rhodes, the group's founder, is being scrutinized in connection with the attack on the U.S. Capitol on Jan. 6.

Federal prosecutors have charged members of the Oath Keepers and Proud Boys with conspiracy in connection with the Capitol riot. What do those cases tell us about advance planning for the violence?

The founder of the Oath Keepers militia had a phone call with a member of the group who minutes later took part in a military-style "stack" formation to breach the Capitol on Jan. 6, prosecutors say.

The Justice Department charged six more members of a far-right militia group for allegedly plotting ahead of the Jan. 6 Capitol insurrection. At least three others were already charged from the group.
