Monday evening, during the first stop of Clinton’s book tour for her new campaign memoir, What Happened, the evening’s host, Lissa Muscatine, co-owner of the popular Washington bookstore Politics and Prose, told the crowd that Clinton and her husband, former President Bill Clinton, had purchased a number of pizzas from Comet Ping Pong and sent them to a local after-school literacy program.

“I told you what was going on and you responded instantly and were so supportive,” recalled Muscatine, whose bookstore is located just down the street from the pizza place. “A few days after that, you and your husband said, ‘What can we do to support Comet?’”

On Dec. 4, 2016, Edgar Welch fired an AR-15 rifle in the establishment. It was later reported that Welch had driven from his home in North Carolina to “investigate” the unsubstantiated claim that Clinton and Podesta had secretly run a child sex ring in the basement of the pizza place. No one was hurt, but the incident had a chilling effect in Washington, where the vitriol of the 2016 campaign had yet to feel so close. Welch was later sentenced to four years in prison.
