Washington Post: “During his four years in office, Trump never strictly followed the rules and customs for handling sensitive government documents, according to 14 officials from his administration, most of whom spoke on the condition of anonymity to discuss what they called Trump’s mishandling of classified information.”
“He took transcripts of his calls with foreign leaders as well as photos and charts used in his intelligence briefings to his private residence with no explanation. He demanded that letters he exchanged with North Korean dictator Kim Jong Un be kept close at hand so he could show them off to visitors. Documents that would ordinarily be kept under lock and key mingled with piles of newspaper articles in Trump’s living quarters and in a dining room that he used as an informal office.”
