This overview of pizzagate is excellent. It gives the history of pizzagate with a fair amount of detail but not so much as to be overwhelming. But enough detail to be thorough. And this would be a great intro to share with people who ask "what is pizzagate." FYI, it does have some disturbing images. Therefore, I would highly recommend you watch this before you share. https://www.youtube.com/watch?v=K6vvx2rHid0
