In Washington, D.C., an armed North Carolina man was arrested Sunday after walking into the popular pizza restaurant Comet Ping Pong and then firing at least one shot. For weeks, right-wing websites have been spreading conspiracy theories about the restaurant, claiming Hillary Clinton and other prominent Democrats were running a child sex ring from the restaurant’s back rooms. The fake news story became known as “Pizzagate.” The North Carolina man, Edgar Maddison Welch, told police he traveled to D.C. to “self-investigate” the story. He has been charged with assault with a dangerous weapon.
