Except... he addresses several of those issues, and why he and Elijah Cummings have jointly chosen to investigate some things, not investigate others (yet), and the legal limitations of what the Joint Oversight Committee can actually do.
There were several people asking about Trump's tax returns, for example, and quoting Chaffetz before the election saying, "Everyone has to open their kimono and show everything, if they want to be President".
But the fact of the matter is, there is no legal requirement for the President to release his tax returns. And yeah, his answer becomes a mealy blowjob for Trump. But the point is that they do not have the power to compel him to do so. He laughs about it, and agrees with the crowd, but he and Cummings are powerless to do anything about it.
He would have left with the idea that he's doing a good enough job representing his constituents that he need not fear for his life.
This right here is why I made my comment.
Yelling incoherently at someone simply makes them stop listening, and prevents any possibility of discourse.
Chaffetz goes home from that event the Winner, because he kept his cool, and the audience failed to. Period. Nothing substantive is gained.
However, imagine this: On the stage are two chairs facing each other. Chaffetz points to someone with their hand raised to ask a question. They come up on stage, sit across from him, and ask their question into the microphone. He then takes the mic and responds directly to the person. Looking them in the eye, face to face, in conversation.
It would have changed the ENTIRE dynamic of the room. Instead of "us" being on stage and everyone else in the room being "them", the dynamic would have changed. It would have been "us on stage talking" while the room became listeners to their conversation.
THIS is how you change bad policy. Not by making pithy signs and screaming incoherently as a crowd.
At least that's the position I am taking for the next 10 years.
