A “Stand With Comet” Facebook event set up the day of the shooting (in which no one was injured) garnered more than 2,000 RSVPs with an additional 4,000-plus people interested. The man behind that event doesn’t have any affiliation with Comet Ping Pong. Erick Sanchez just likes the pizza. just likes the pizza which kind of?

so friends with CPP, Joe Biden, and the DC Policechief, is a major shill for hill, and likes pizza. he also has some clip with a panda among the tweets, but cought be coincidence. https://mobile.twitter.com/erickmsanchez/status/872812291925970945
