Before the confrontation, Beeks joined with a group of Oath Keepers while walking from the Ellipse, where Trump had held a “Stop the Steal” rally, to the Capitol, officials said. Unlike the camouflage-combat attire of many in the group, Beeks was wearing a Michael Jackson “BAD” world tour jacket and a black helmet, and he was carrying what appeared to be a homemade black shield, officials said.
