Avalon - A committee member receives a letter about a candidate and refers it to the committee who orders an investigation. The investigation concludes that the charges are totally unsubstantiated and reports back their findings. The committee holds their hearing and the candidate is confirmed along party lines. The candidate's reputation is not unfairly smeared, justice is served and the country moves on. Please explain why this did not happen.
