A federal Justice of the Peace choose unsealed on Wednesday extra parts of the affidavit that the F.B.I. used final summer time to acquire a warrant to seek for delicate paperwork at Mar-a-Lago, former President Donald J. Trump’s non-public membership and residence in Florida, revealing a couple of new particulars about how that extraordinary course of had unfolded.

The newly unredacted sections of the affidavit instructed that prosecutors had based mostly their search, partially, on surveillance footage from cameras close to a storage room within the basement of Mar-a-Lago displaying Walt Nauta, a private aide to Mr. Trump, transferring dozens of bins out and in of the room days earlier than federal prosecutors arrived to gather any delicate data nonetheless in Mr. Trump’s possession.

Much of the fabric within the affidavit unsealed on Wednesday had already been made public within the expansive indictment of Mr. Trump and Mr. Nauta issued in Miami final month. That indictment charged the previous president with 31 counts of illegally retaining nationwide protection data and a separate rely of conspiring with Mr. Nauta to impede the federal government’s efforts to reclaim them.

The choose who ordered the unsealing, Bruce E. Reinhart, had issued two earlier orders unsealing separate parts of the warrant affidavit in response to media requests.

The newly revealed data included {a photograph} of dozens of bins within the Mar-a-Lago storage room, in addition to an in depth description of the assorted angles caught by the safety cameras exterior the room.

“The door to the storage room was painted gold and had no other markings on it,” the F.B.I. agent who drafted the affidavit wrote. “The door to the storage room is located approximately midway up the wall and is reachable by several wooden stairs.”

Echoing the indictment, the unredacted affidavit additionally famous that between May 24, 2022, and June 1, 2022, Mr. Nauta took 64 bins out of the storage room at Mar-a-Lago however put again solely 25 or 30 of them.

“The current location of the boxes removed from the storage room but not returned to it is unknown,” the affidavit mentioned.

The newly launched model of the affidavit didn’t, nevertheless, disclose all the explanations that federal prosecutors believed delicate data remained at Mar-a-Lago even after two earlier makes an attempt to retrieve them from Mr. Trump.

In January 2022, Mr. Trump despatched 15 bins of presidency data from Mar-a-Lago to the National Archives, which found they contained almost 200 categorized paperwork. That prompted federal prosecutors to challenge a subpoena in May for any extra supplies bearing categorized markings nonetheless in Mr. Trump’s possession. In June 2022, after conducting what was meant to be a diligent search of Mar-a-Lago, one of many former president’s attorneys, M. Evan Corcoran, gave the federal government one other batch of 38 categorized paperwork.

But even after these two preliminary teams of paperwork have been returned, prosecutors suspected that Mr. Trump nonetheless had much more categorized supplies in his residence at Mar-a-Lago and in an adjoining space. The surveillance footage of Mr. Nauta was apparently just one piece of proof underpinning that perception. A protracted part of the affidavit that follows the assertion by prosecutors that Mr. Trump had not returned every part he ought to have stays underneath seal.

It was Judge Reinhart who issued the Mar-a-Lago search warrant last August, leading to federal brokers hauling away greater than 100 paperwork bearing classification markings.

Judge Reinhart has additionally been assigned because the Justice of the Peace choose to the prosecution of Mr. Trump and Mr. Nauta. Mr. Nauta is scheduled to be arraigned in Federal District Court in Miami on Thursday.

In response to the unsealing of recent parts of the warrant, Steven Cheung, a spokesman for Mr. Trump, mentioned as he has earlier than that the previous president “has consistently been in full compliance with the Presidential Records Act” and that he had been useful to the Justice Department. Officials within the division have mentioned that the details contradict such assertions.

Among the brand new particulars revealed on Wednesday was that neither Mr. Corcoran nor one other lawyer for Mr. Trump had instructed prosecutors that the previous president had declassified any of the 38 categorized paperwork handed over final June. That omission appeared to contradict an earlier assertion the attorneys had made to the federal government, claiming that as president, Mr. Trump had “absolute authority” to declassify any materials he needed.

The newly unredacted parts of the affidavit additionally say that Mr. Corcoran instructed the federal government that he had been knowledgeable that there have been no categorized data “in any private office space or other location in Mar-a-Lago” — an assertion that the search of the property revealed to be unfaithful.

In March, a federal choose in Washington compelled Mr. Corcoran to offer data and to testify to a grand jury investigating the case, working across the common protections of attorney-client privilege as a result of she believed that Mr. Trump had misled Mr. Corcoran about the place delicate data have been saved at Mar-a-Lago.
