Motivations of shop owner:
"The owner of the repair store's political motivations came to light  in the interview with CBS News and a few other reporters, raising even  more questions about the veracity of how this supposed laptop became  public.
                 
 MacIsaac, the owner, said several times how he felt Mr. Trump was  treated unfairly during his impeachment trial and suggested if the  alleged documents are true, the "sham" impeachment was reason to release  them. He also repeatedly mentioned his girlfriend left him after he  voted for Trump in 2016.
Asked about the timeline of events detailed in the Post story,  MacIsaac told CBS News that a man who identified himself as Hunter Biden  dropped off three laptops to have them repaired in April 2019. He said  the man never paid him for the repairs and did not return to pick them  up.  Standing in his shop on Wednesday, MacIsaac admitted he was  unable to confirm it was actually Hunter Biden who dropped off the  laptop because he is "legally blind" and only realized it was the former  vice president's son when Hunter stated his name for the point of  contact.
The Mac Shop is equipped with indoor cameras that  preserve recordings for two months. MacIsaac said he did not realize the  significance of the laptops until after the footage was automatically  deleted. 
MacIsaac also would not reveal when he first looked  through the data, and refused to provide key details about his handling  of the material. Asked by CBS News if he actually saw the email  purportedly from Pozharskyi, he repeatedly said "no comment" before  saying he "believed" he had. MacIsaac refused to answer in any detail  whether or why he would have searched through the laptop to find a  four-year-old email, which seemingly appears to be an innocuous message  about arranging a meeting for coffee.
MacIsaacprovided no additional details to CBS News to corroborate he saw these alleged documents."
