“It is also our understanding that roughly two dozen boxes of original presidential records were kept in the Residence of the White House over the course of President Trump’s last year in office and have not been transferred to NARA, despite a determination by Pat Cipollone in the final days of the administration that they need to be,” wrote Gary Stern, the agency’s chief counsel, in an email to Trump lawyers in May 2021, according to a copy reviewed by The Washington Post.

The email shows NARA officials were concerned about Trump keeping dozens of boxes of official records even before he left the White House — concerns that only grew in the coming months as Trump repeatedly declined to return the records. It also showed that Trump’s lawyers had concerns about Trump taking the documents and agreed that the boxes should be returned — at least according to the top Archives officials — while Trump kept the documents.
