I mean knowing what we know about Rudy and his technology abilities, it's not that difficult for me to dismiss anything he or related cronies suggest out of hand.
I agree, Rudy Giuliani has spread quite a bit of disinfo over the past 4 years. The claim here that is supposedly supported by a receipt is that Hunter left the computer at a repair shop and never paid the bill. In adherence with the store contract they took ownership of the laptop after some time. When they looked at the hard drive they thought they saw illegal activity and turned it into the FBI after making a clone of the drives which is what Rudy claims he has.
If Rudy was not behind the last October surprise he was at least in the loop — he openly boasted about having advance knowledge of the Comey letter.
