There is proof that his past was scrubbed. He’s in the phone book for Los Alamos the years he claimed to work there. He’s also revealed names of colleagues he had and they have confirmed he worked there. He also went back to Los Alamos with a camera and walked around the building, introducing who he was with to people that knew him from his time there, and he could easily navigate the building as if he worked there. He was also on the front page of the local paper for Los Alamos after modifying his own car with a jet engine, and the paper identified him as a physicist working at Los Alamos. Yet, Los Alamos claimed to have no record of him ever working there. The same from MIT, and the same from the hospital he was born in claiming he was never born there but he has shown his birth certificate. That’s the proof his past was scrubbed.
