I watched much of Michael Cohen's testimony today, when I could. Much of what I did see was unilluminating, although not unimportant. The best questioner - by far - I saw was Alexandria Ocasio-Cortez. I'll try to link it. She was sharp, succinct and focused, and, most important, elicited important information. She put most of the lawyers on the panel to shame, and not by a little. link.
it's short. You should watch it.
