I've watched that interview, congress would ask a loaded question, framed in a fallacy[1], the chair would start answering it, and the congresscritter would interrupt him and throw a tantrum. Repeat 5x.
It wasn't a good look. For the congresscritter.
(I wonder how much money he's gotten from Sam, CZ, and Coinbase...)
[1] The fallacy in question is the congresscritter's claim[2] that a security can't also be a commodity. This is trivially disprovable by a simple example - an isolated company town using scrip, where the scrip also happens to be company stock.
[2] Whenever the chair would start responding to the fallacy, the congresscritter shouts over him, because if he doesn't, his argument-in-the-form-of-a-question falls to pieces.
