Though Trump has said he had declassified all of the documents at Mar-a-Lago, his lawyers did not suggest that during the visit and instead "handled them in a manner that suggested counsel believed that the documents were classified," according to the document.
FBI agents who went there to receive additional materials were given "a single Redweld envelope, double-wrapped in tape, containing the documents," the filing states.
That envelope, according to the FBI, contained 38 unique documents with classification markings, including five documents marked confidential, 16 marked secret and 17 marked top secret.
During that visit, the document says, Trump's lawyers told investigators that all the records that had come from the White House were stored in one location — a Mar-a-Lago storage room — and that "there were no other records stored in any private office space or other location at the Premises and that all available boxes were searched."
After that, though, the Justice Department, which had subpoenaed video footage for the property, "developed evidence that government records were likely concealed and removed from the Storage Room and that efforts were likely taken to obstruct the government's investigation." The filing does not identify the individuals who may have relocated the boxes.
In their August search, agents found classified documents both in the storage room as well as in the former president's office — including three classified documents found not in boxes, but in office desks.
"That the FBI, in a matter of hours, recovered twice as many documents with classification markings as the 'diligent search' that the former President's counsel and other representatives had weeks to perform calls into serious question the representations made in the June 3 certification and casts doubt on the extent of cooperation in this matter," the document states.
