Instead, here’s what a fair system might look like: Congress should empower an independent arbiter to investigate complaints — like a Government Accountability Office, with trained experts in the field. Clearly understood mechanisms for reporting should be established. A timetable should be set that ensures complaints receive a prompt response. Both the accuser and the accused could submit questions and would have access to trained advocates and free legal consultation.

The independent arbiter would then make a nonbinding proposal addressing what happened and what should be done. It could include a call to resign or for censure, or a range of other responses tailored to the findings.
