As seen on Hart's documentary, Hart proceeded to the dressing rooms and questioned Michaels, who pleaded that he knew nothing about what had taken place and was equally outraged. McMahon locked himself in his office with Pat Patterson and other agents. Mark Calaway, known in professional wrestling as The Undertaker, furious with McMahon, banged on the door. McMahon opened and was told by Calaway he had to apologize to Hart. As recounted in Michaels' autobiography, he was told by McMahon not to say anything about the screwjob to anybody, because McMahon needed to have everyone think that it was only him involved. Michaels offered his assurance that he would not carry the title belt out the next day on "Raw" and would refuse to say anything derogatory about Hart, Hart states in his autobiography that Undertaker and many wrestlers in the back supported him and it would have become mutiny. Hart proceeded to the dressing room to shower and change after discovering that McMahon, Brisco, and Slaughter had locked themselves in McMahon's office. When McMahon went to Hart's dressing room and tried to explain himself, Hart angrily rebuffed him and warned him to leave immediately or risk being punched.
