Fourteen of 15 boxes recovered earlier this year from former President Donald Trump's Florida estate contained confidential documents

, many of them top secret, mixed with newspapers, magazines and personal correspondence, according to an FBI affidavit released Friday.

No space in Trump's Mar-a-Lago mansion was licensed for the storage of classified material

, the court papers say, which laid out the FBI's arguments for raiding the property this month, including "probable cause to believe will find evidence of obstruction.”

The 32-page affidavit —

heavily redacted to protect the safety of witnesses and law enforcement officials, and “the integrity of the ongoing investigation” — provides the most detailed description to date of official documents that were stored at Mar-a-Lago. long after Trump left the White House.

It also reveals how great the government's concerns were that the documents were being held there illegally.

And it is that Donald Trump took more than 700 pages of classified documents,

including some related to the most covert intelligence operations in the country,

to his private club and residence in Florida when he left the White House in January 2021

, according to a letter that the National Archives sent their lawyers this year.

The letter, dated May 10 and written by Acting US Archivist Debra Steidel Wall to one of Trump's attorneys, M. Evan Corcoran, described the

state of alarm at the Justice Department as officials they began to realize how delicate the documents were.

It also suggested that the department's top prosecutors and members of the intelligence community were slow to conduct a damage assessment on the removal of the White House documents while Trump's lawyers tried to argue that some of the materials could be have been protected by executive privilege.

The letter was revealed Monday night by one of Trump's media allies

, John Solomon, who is also one of the former president's representatives to the archives.

The archives then proceeded to publish the letter on Tuesday.

The New York Times reported Monday that investigators had recovered more than 300

classified-labeled documents from Mar-a-Lago, Trump's residence and private club, and that each document could be several pages long.

At one point in the letter,

Wall told Corcoran that Biden had agreed with her and others that Trump's attempts to assert executive privilege over the materials were baseless.

But the letter never indicated that Biden was in charge of the decision to reject Trump's privilege claims

or that it had anything to do with the Mar-a-Lago search, as Solomon implied.

In fact, the letter could further implicate Trump in a possible crime.

It confirms, for example, that the former president had kept documents related to the Special Access Programs, some of the best-kept secrets in the country, at Mar-a-Lago before the FBI searched the property.

The document also delved into the back-and-forth between the files and Trump's lawyers

on how to handle the recovery of the papers.

Some aspects of this new timeline, revealed by Wall's letter and email, further undermine the claims of Trump's legal team

, which has said that federal officials could simply have requested the material at any time and that the matter was just an amicable negotiation in progress.

Solomon's decision to release the letter did more than confirm that Trump had been keeping some of the country's best-kept secrets

at his relatively insecure beachfront club in Florida.
