It sounded like no one even proofread and edited their questions or lines of reasoning. There should be a panel of non-partisan people, not even experts, taking the dumb out of their questions before they engage. It was a waste of time. Even some strong questions and ideas were shutdown because they couldn't formulate it, and then the internet turned it into another way to laugh at congress.
Maybe there needs to be an old-lawyer to SME translator doing the talking too. This person questions a SME on behalf of the senators and they can speak up or seek clarification when needed. Proofread questions and competent speech.
