I remember one of the first things I heard was that a bullet struck the teleprompter and he was hit by broken glass. I never heard anything about it after that, so I assumed it was just false; but it made a whole lot of sense at the time.
Sure it would, and I don't want to give credence to conspiracy theories, but the teleprompter belongs to Trump's campaign, so if it's going to be released, the call will have to come from inside the house.
