Why Did Trump Resist Returning the Classified Documents?

New York 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.”
