But 18 former top Trump administration officials tell CNN they never heard any such order issued during their time working for Trump, and that they believe the claim to be patently false.

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 it.”

Mick Mulvaney, who succeeded Kelly as acting White House chief of staff, also dismissed the idea and told CNN he was “not aware of a general standing order” during his tenure.

In addition, CNN spoke with former national security and intelligence officials as well as White House lawyers and Justice Department officials. Taken together, their tenure covers all four years of the Trump administration, and many served in positions where they would either be included in the declassification process, or at the very least, be aware of such orders.
