Sure - the right wing militias (and Roger Stone) had formed a plan to trap the congress members in the tunnels that connect the federal buildings in DC so that they could kill them. The Oath Keepers were also involved in this plan, which was revealed as evidence in various court proceedings. The OK and PB trials were extremely damning.

Even without Tarrio present, the Proud Boys were involved in preventing police from sealing off various tunnel entrances. Some militia individuals entered the tunnels in accordance with those same plans. The tunnels were also occupied by military personnel at that time. So there were various groups of individuals at various locations interacting with security forces (‘points of contact’) involved in compromising the security of the congress members, yet the only blood shed was the AF lady who tried crawling through the broken window in the door to the chamber.
