The Presidential Records Act (PRA) of 1978, 44 U.S.C. §§ 2201–2207, is an Act of the United States Congress governing the official records of Presidents and Vice Presidents created or received after January 20, 1981, and mandating the preservation of all presidential records.
Probably a good idea giving a link to the actual law because it appears that many of our local MAGA supporters can't use a search engine.
Some of Trump's presidential records were boxed and sent to his golf course and by law required the National Archives to retrieve those records. According to the Archives, "some of the Trump records taken to Mar-a-Lago were clearly marked as classified, including documents at ‘top secret’ level".
Included were correspondence from Kim Jong-un and the map "Mr. Trump famously drew on with a black Sharpie marker to demonstrate the track of Hurricane Dorian heading toward Alabama in 2019 to back up a declaration he had made on Twitter that contradicted weather forecasts".
The tin foil MAGA hat wearing conspiracy theory people will never understand facts and will continue to call the facts "fake news".
