I’m guessing PDJT’s comments are to motivate the Anons to start digging so they can further discredit the attack dog going after him (President Trump). I looked at the 1987 Liverpool High School (New York) yearbook but I couldn’t get into the photos without registering and logging in. There is a John Smith, and his wiki page says Jack was indeed born John. We’d need to see the photo to verify it’s a younger version of the same guy. I also tried to look at the picture of the football and baseball teams but I couldn’t see those either.
