This was taken when Trump was relocating from Maralago to Bedminster NJ for the summer. Honestly who the heck knows what was in those boxes. They could not have been too heavy since the female is easily carrying one and a male seems to have no trouble carrying two boxes stacked on top of each other. If they were full of paper they would have been quite heavy.
I have all sorts of mementos and Knick knacks stored in similar file boxes. They are handy to use. With removable tops they don’t need to be taped or folded shut.
Good points, but how do you know when this footage was taken? Have you seen it before? I noticed there’s a lot of regular luggage also being taken on board, so this flight clearly wasn’t just to remove the boxes, which gives credence to your claim.
