You need to ask him.
“So what was Giuliani doing with it?”
If I remember correctly, the fellow who is the owner of the computer repair store in Delaware, once he scanned what was on the drive, realized that it documented all kind of laws being broken, The local Delaware law enforcement would not get involved (Bidens are from Delaware), so the owner gave it to Rudy, knowing Rudy is one of the few upright, honest person, who would do the right thing and not cover it up.
