The Senate needs to oversee federal investigation of the attack and ransacking of our national Capitol, through Judiciary and perhaps Homeland Security. We may also be the client in federal civil suits for damages and for restraining orders, likely also under Judiciary purview.

The Senate will need to conduct security review of what happened and what went wrong, likely through Rules, Homeland and Judiciary. The Senate Ethics Committee also must consider the expulsion, or censure and punishment, of Sens. Cruz, Hawley, and perhaps others.

Because Congress has protections from DOJ under separation of powers, specifically Speech and Debate Clause, significant investigation will need to be done in Senate.

Because of massive potential conflict of interest, Sens Cruz, Hawley and Johnson (at least) need to be off all relevant committees reviewing this matter until the investigation of their role is complete.
