A member of the far-right Oath Keepers extremist group has pleaded guilty to seditious conspiracy and obstruction in connection with the Jan. 6 attack on the U.S. Capitol and agreed to cooperate with the government.

Brian Ulrich entered his guilty plea at a virtual hearing Friday in U.S. District Court in Washington, D.C. The 44-year-old from Guyton, Ga., is the second Oath Keeper to plead guilty to sedition charges in the highest-profile case to emerge from the federal investigation into the Capitol riot.

Ulrich is one of 11 Oath Keepers, including the group’s founder Stewart Rhodes, to be charged with seditious conspiracy and other crimes for allegedly plotting to use force to prevent Congress’ Jan. 6 certification of President Biden’s election win.
