Capitol attack investigators zero in on far-right Oath Keepers and Proud Boys

Panel appears to believe militias coordinated to physically stop certification of Joe Biden's election victory on 6 January last year

The House select committee investigating January 6 appears to believe the Capitol attack included a coordinated assault perpetrated by the Oath Keepers and the Proud Boys militia groups that sought to physically stop the certification of Joe Biden's election victory.

The panel's working theory - which has not been previously reported though the justice department has indicted some militia group leaders - crystallized this week after obtaining evidence of the coordination in testimony and non-public video, according to two sources familiar with the matter.
