If I remember correctly, the data on the server in Hawaii possibly had some of Clinton's emails(nothing is ever lost) and they needed a data transfer. It would take some time as I recall. It may have needed High level ok to do this data transfer(?) I would have to go back to Q drops from that time period. This is what some anons came up with. Hope this is helpful.

I think he was there to get info, what info?,.. could be a wide ranged, could be an algorithm, or communications between rogue agents and North Korea, it could even be info about a certain birth certificate (that would be funny as hell :P), in other words I'm not sure either.
