From the NY Times:
Although Trump White House officials were warned about the proper handling of sensitive material, aides said Mr. Trump had little interest in the security of government documents or protocols to keep them protected.
Early on, Mr. Trump became known among his staff as a hoarder who threw all manner of paper — sensitive material, news clips and various other items — into cardboard boxes that a valet or other personal aide would cart around with him wherever he went.
Mr. Trump repeatedly had material sent up to the White House residence, and it was not always clear what happened to it. He sometimes asked to keep material after his intelligence briefings, but aides said he was so uninterested in the paperwork during the briefings themselves that they never understood what he wanted it for.
Donald Trump was carting around Top Secret documents in a cardboard box wherever he went? What was he doing? Giving them away? Showing them to our enemies in exchange for money (or worse)? It would not surprise me one bit if Trump was deliberately handing them out (or selling them) to people. What I want to know is how many of those documents ended up in the hands of our enemies?
