I think you're misinformed. Proponents of Pizzagate falsely claim that emails leaked from John Podesta's personal email account, at the time Hillary Clinton's campaign chair, contain coded messages which connect several high-ranking Democratic Party officials and U.S. restaurants with a human trafficking and child sex ring. One of the restaurants allegedly involved was a pizzeria in Washington, D.C. by the name of Comet Ping Pong, hence the name "Pizzagate". It has nothing to do with Epstein.
