Eighteen former top Trump officials said they never heard any "standard declassification" order issued during their time working for Trump. Via CNN:

Several officials laughed at the notion. One senior administration official called it "bullsh*t." Two of Trump's former chiefs of staff went on the record to knock down the claim.

"Nothing approaching an order that foolish was ever given," said John Kelly, who served as Trump's chief of staff for 17 months from 2017 to 2019. "And I can't imagine anyone that worked at the White House after me that would have simply shrugged their shoulders and allowed that order to go forward without dying in the ditch trying to stop.....

Multiple sources said they believed that Trump's claim the documents were declassified was nothing more than a transparent attempt to try to defend himself for taking the documents to Mar-a-Lago.

"There is a process to declassify, the president can't just wave a magic wand," a former senior Trump White House official said.
