ProWrestlingSheet.com is reporting that Jenn Sterger who hosted the conference stated during an interview on the Collider Bodyslam podcast that CM Punk was backstage. Allegedly he was there to pick up shirts from Pro Wrestling Tees. They also noted that no one at the event would confirm or deny that he would be at ALL IN despite him doing an autograph appearance at Pro Wrestling Tees the day before.
“If you got your tickets at face value for this event, I’m just saying it literally might be the best in the world,” Sterger told the show. “I will only say someone wearing sweatpants and training for something walked into the back of the building that the press conference was in — with marks, mind you, lining the entire sidewalks in the front of the building — and I just kept thinking ‘if they knew you were back here, they would literally tear down the front of the store.’”
