Among the bizarre behaviors of the sitting president, this one stands out. Donald Trump has claimed repeatedly Hillary Clinton should be prosecuted for destroying emails she "acid washed" from her personal server's hard drive (her staff used a free app called BleachBit). Politico reports Trump destroys official documents personally:
Armed with rolls of clear Scotch tape, [Solomon] Lartey and his colleagues would sift through large piles of shredded paper and put them back together, he said, “like a jigsaw puzzle.” Sometimes the papers would just be split down the middle, but other times they would be torn into pieces so small they looked like confetti.
It was a painstaking process that was the result of a clash between legal requirements to preserve White House records and President Donald Trump’s odd and enduring habit of ripping up papers when he’s done with them — what some people described as his unofficial “filing system.”
Under the Presidential Records Act, the White House must preserve all memos, letters, emails and papers that the president touches, sending them to the National Archives for safekeeping as historical records.
Donald Trump's habit when he is finished with documents is to tear them up and throw them in the trash or onto the floor. To prevent violations of law (if willful destruction of presidential records is not), staffers learned to collect the fragments and ferry them to the records office across the street to be reassembled by hand by Lartey (54, earning $65,969 per year) and his team.
