The whole locks business never happened. But the FBI did ask that the material in the room be better secured. I suspect they suspected not all the requested materials had been turned over. Hence the request they be better secured and interviews with staff (and perhaps Secret Service personnel) working at Mar-a-Lago.
June 3: Bratt and three FBI agents meet with Bobb and Corcoran at Mar-a-Lago and receive the documents gathered in response to the May 11 subpoena. Trump’s lawyers later write in a court filing that the group is greeted in the dining room by Trump, who tells the lawyers to give Bratt and his agents anything they need. The filing indicates that Bratt tours a storage area where documents were stored. Bobb later tells The Washington Post that Bratt opened some of the boxes and flipped through the material inside. In its Aug. 30 court filing, the Justice Department disputed that, telling a judge that Trump’s lawyer “explicitly prohibited government personnel from opening or looking inside any of the boxes that remained in the storage room.” The filing indicates that the custodian of the records signed a written statement certifying: “Based upon the information that has been provided to me, I am authorized to certify, on behalf of the Office of Donald J. Trump, the following: a. A diligent search was conducted of the boxes that were moved from the White House to Florida; b. This search was conducted after receipt of the subpoena, in order to locate any and all documents that are responsive to the subpoena; c. Any and all responsive documents accompany this certification.” The Post has reported that Bobb signed the document.
The Justice Department says later that Bratt was given a single folder of documents that analysis shows includes 38 unique documents bearing classification markings, including five documents marked as confidential, 16 documents marked as secret, and 17 documents marked as top secret.
June 8: Bratt emails Corcoran asking that any documents still at Mar-a-Lago be kept in the storage room and not disturbed. “As I previously indicated to you, Mar-a-Lago does not include a secure location authorized for the storage of classified information,” he writes. “As such, it appears that since the time classified documents were removed from the secure facilities at the White House and moved to Mar-a-Lago on or around January 20, 2021, they have not been handled in an appropriate manner or stored in an appropriate location. Accordingly, we ask that the room at Mar-a-Lago where the documents had been stored be secured and that all of the boxes that were moved from the White House to Mar-a-Lago (along with any other items in that room) be preserved in that room in their current condition until further notice,” he wrote.
